For instance, the Sirt-1 protein interactome and Sirt family second order interactome[5][6] is the network involving Sirt-1 and its directly interacting proteins where as second order interactome illustrates interactions up to second order of neighbors (Neighbors of neighbors). Subsequently, proteome-scale interactome mapping projects for eukaryotes have been carried out in yeast, worm and fly (6– 10). NLM A Proteome-wide Binary Interactome Map Based on literature-curated information, the human interactome appears to be restricted to a narrow dense zone, suggesting that half of the human proteome participates only rarely in the interactome network. Doan M, Sebastian JA, Caicedo JC, Siegert S, Roch A, Turner TR, Mykhailova O, Pinto RN, McQuin C, Goodman A, Parsons MJ, Wolkenhauer O, Hennig H, Singh S, Wilson A, Acker JP, Rees P, Kolios MC, Carpenter AE. Although a preliminary portrait of the red blood cell proteome and interactome has already been provided, the recent identification of 1578 gene products from the erythrocyte cytosol asks for an updated and improved view. First, scientists try to elucidate the systems properties of interactomes, e.g. Wang L, Eftekhari P, Schachner D, Ignatova ID, Palme V, Schilcher N, Ladurner A, Heiss EH, Stangl H, Dirsch VM, Atanasov AG. Additional factors may have roles in protein interactions that have yet to be incorporated in interactomes. In fact, two groups using the same techniques on the same organism found less than 30% interactions in common. [74] have coined the term "party hub" for hubs whose expression is correlated with its interaction partners. By this means, the complex protein architectures and interactions essential to the genesis of phenotypic diversity may initially emerge by non-adaptive mechanisms. The degree distribution describes the number of proteins that have a certain number of connections. However, this approach has certain limitations, primarily because the source data may not be reliable (e.g. To characterize the impact of Hsp90 on the proteome and define the Hsp90 interactome, we used a combination of targeted affinity purification-mass spectrometry (AP-MS) and whole-cell quantitative proteomic approaches to identify proteins that interact with Hsp90 and depend on Hsp90 for stability. the topology of its interactions. by Tristan Cardon. For instance, even within a proteome two proteins may interact but their paralogs may not. In fact, they share many properties with biological or social networks. Both methods can be used in a high-throughput (HTP) fashion. [27], Protein interaction networks have been used to predict the function of proteins of unknown functions. The interactome and proteomic responses of ALKBH7 in cell lines by in-depth proteomics analysis Shu Meng1†, Shaohua Zhan1,2,6†, Wanchen Dou3*and Wei Ge1,4,5* Abstract Background: ALKBH7 is a mitochondrial protein, involved in programmed necrosis, fatty acid metabolism, cell cycle regulation, and prostate cancer disease. Interaction networks can be analyzed using the tools of graph theory. While no biological interactomes have been fully characterized, over 90% of proteins in Saccharomyces cerevisiae have been screened and their interactions characterized, making it the best-characterized interactome. The N protein had only six proximity interactions while M had 938 or ~10% of the cellular proteome. For instance, it has been estimated that typical Y2H screens detect only 25% or so of all interactions in an interactome.

Another extensively studied type of interactome is the protein–DNA interactome, also called a gene-regulatory network, a network formed by transcription factors, chromatin regulatory proteins, and their target genes. Some of the observations made from this study are that there were twice as many negative as positive interactions, negative interactions were more informative than positive interactions, and genes with more connections were more likely to result in lethality when disrupted.[9]. The others have used extensive yeast two-hybrid (Y2H) screens. Most commonly, interactome refers to protein–protein interaction (PPI) network (PIN) or subsets thereof. Koch M, Cegla J, Jones B, Lu Y, Mallat Z, Blagborough AM, Angrisano F, Baum J. Malar J. In parallel, pathway analysis confirmed the validity of observations about the SEC23B gene role in CDA II in a fast and unbiased way. Larger estimates often include indirect or predicted interactions, often from affinity purification/mass spectrometry (AP/MS) studies.[7]. ChromID identifies the protein interactome at chromatin marks. The ultimate goal is to assign tandem MS spectra to peptides and subsequently infer proteins and their abundance. The term specifically refers to physical interactions among molecules (such as those among proteins, also known as protein–protein interactions, PPIs; or between small molecules and proteins ) but can also describe sets of indirect interactions among genes (genetic interactions).

Inserm U1192, University Lille, CHU Lille, laboratory Protéomique Réponse Inflammatoire Spectrométrie de Masse (PRISM), F-59000 Lille, France.  |  For instance, most analytical methods that work fine with soluble proteins deal poorly with membrane proteins. These days, scientists not only want to identify individual genes and proteins, but also all the genes of one cell (genome), all gene readouts (transcriptome), all proteins (proteome) and their partners (interactome). [18] In addition, proteins and their interactions change during evolution and thus may have been lost or gained. TEXT. Interactomics is an example of "top-down" systems biology, which takes an overhead, as well as overall, view of a biosystem or organism. In molecular biology, an interactome is the whole set of molecular interactions in a particular cell. [78] Consistent with a role for date-hubs in connecting different processes, in yeast the number of binary interactions of a given protein is correlated to the number of phenotypes observed for the corresponding mutant gene in different physiological conditions. establish the SARS-CoV-2 intraviral and virus-host protein-protein interaction networks and reveal the overall proteome signature in PBMCS from COVID-19 patients by quantitative proteomic analysis. However, the exact roles of ALKBH7 and the underlying molecular mechanisms remain mysterious. In this paper, we exploit data available from recent literature to compile a nonredundant list of 1989 proteins and elaborate it with pathway and network analyses. To reach this target, we are mapping binary protein-protein interactions by systematically interrogating all pairwise combinations of predicted gene products in defined search spaces using proteome-scale technologies. Here, PPIs from one organism are used to predict interactions among homologous proteins in another organism ("interologs"). [28][29] This is usually based on the assumption that uncharacterized proteins have similar functions as their interacting proteins (guilt by association). However, there are two important goals of such analyses. 2020 Dec;14:17-27. doi: 10.1016/j.ijpddr.2020.07.002. The word "interactome" was originally coined in 1999 by a group of French scientists headed by Bernard Jacq. Such analyses are mainly carried out using bioinformatics methods and include the following, among many others: First, the coverage and quality of an interactome has to be evaluated. Thank you for submitting your article "A computational interactome and functional annotation for the human proteome" for consideration by eLife. Once an interactome has been created, there are numerous ways to analyze its properties. [10] Interactomics thus aims to compare such networks of interactions (i.e., interactomes) between and within species in order to find how the traits of such networks are either preserved or varied. This leads to 30% of all reported interactions being artifacts. [16], Using experimental data as a starting point, homology transfer is one way to predict interactomes. However, the exact roles of ALKBH7 and the underlying molecular mechanisms remain mysterious. Epub 2020 Jul 23. What is interactome? [28][59][60] Species whose interactomes have been studied in some detail include, Recently, the pathogen-host interactomes of Hepatitis C Virus/Human (2008),[63] Epstein Barr virus/Human (2008), Influenza virus/Human (2009) were delineated through HTP to identify essential molecular components for pathogens and for their host's immune system.[64]. Protein interaction networks can be analyzed with the same tool as other networks. Epub 2008 Jul 9. However, none of these interactomes are complete in the sense that they captured all interactions. Large sets of genome-wide and proteomic data are collected, and correlations between different molecules are inferred. Human Interactome project will be the most important project after Genome and Proteome of human species. 2020 Sep 1;117(35):21381-21390. doi: 10.1073/pnas.2001227117. [4] Mathematically, interactomes are generally displayed as graphs. [14] The coverage of an interactome can be assessed by comparing it to benchmarks of well-known interactions that have been found and validated by independent assays. [26] Such methods have been applied for discovering protein interactions on human interactome, specifically the interactome of Membrane proteins[25] and the interactome of Schizophrenia-associated proteins. To characterize the impact of Hsp90 on the proteome and define the Hsp90 interactome, we used a combination of targeted affinity purification-mass spectrometry (AP-MS) and whole-cell quantitative proteomic approaches to identify proteins that interact with Hsp90 and depend on Hsp90 for stability. 2007 Dec;232(11):1391-408. doi: 10.3181/0706-MR-156. Drosophila Interactome Map - FlyBi Project The Drosophila melanogaster genome is one of the best-annotated multi-cellular eukaryotic genomes and yet our knowledge of protein-protein interactions (PPIs), protein complexes and networks in D. melanogaster proteomics is still limited. The resultant decline in the efficiency of selection seems to be sufficient to influence a wide range of attributes at the genomic level in a nonadaptive manner. John Wiley & Sons Ltd: Chichester, Volume 5, pp. Party hubs are found predominantly in AP/MS data sets, whereas date hubs are found predominantly in binary interactome network maps. Co-complex Interactome Network. Michel Salzet. The distribution of properties among the proteins of an interactome has revealed that the interactome networks often have scale-free topology[35] where functional modules within a network indicate specialized subnetworks. Upon network analysis, it is intuitively confirmed that red blood cells likely suffer of exacerbated oxidative stress and continuously strive against protein and cytoskeletal damage. The yeast interactome, i.e. This site needs JavaScript to work properly. Misinteraction Disease theory Open and Collaborative Projects Human Interactome Project: Users are welcome to add and edit contents to compile human interaction molecular pairs. The interactomes based on PPIs should be associated to the proteome of the corresponding species in order to provide a global view ("omic") of all the possible molecular interactions that a protein can present.[2]. Interactomics in 2015 is where genome sequencing was in the late 1990s, given that only a few interactome datasets are available (see table above). Viral protein interactomes consist of interactions among viral or phage proteins. 2019 Nov 29;18(1):381. doi: 10.1186/s12936-019-3016-3. Sumera A, Anuar ND, Radhakrishnan AK, Ibrahim H, Rutt NH, Ismail NH, Tan TM, Baba AA. Such approaches range in terms of complexity from simple co-occurrence statistics of entities that are mentioned together in the same context (e.g. [14] Among the published bacterial interactomes (including partial ones) are. Thus, population size would have to be considered as a potential determinant of the mechanistic pathways underlying long-term phenotypic evolution. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Integrating Genomic, Transcriptomic, and Interactome Data to Improve Peptide and Protein Identification in Shotgun Proteomics. Genes that are connected in such a way form genetic interaction networks. NIH 2. Mizuno and Kikuchi at National Agriculture and Food Research Organization (NARO) in Japan to generate: a comprehensive single-colony fully-sequence-verified rice ORFeome library and a whole-proteome rice interactome. It is difficult to match evolutionarily related proteins in distantly related species. Second, studies may focus on individual proteins and their role in the network. all protein–protein interactions among proteins of Saccharomyces cerevisiae, has been estimated to contain between 10,000 and 30,000 interactions. We detected over 20% of the estimated A549 proteome to be in proximity to at least one of the viral proteins we expressed. (2005) The yeast interactome. Molecular interactions can occur between molecules belonging to different biochemical families (proteins, nucleic acids, lipids, carbohydrates, etc.) RNA-binding IDRs are enriched in amino acids typically found at the protein–RNA interfaces in globular domains, including tyrosine, arginine and lysine. Similar protein interactome studies in different contexts and with varying degrees of overlap between datasets soon followed (Stukalov et al., 2020). by Tristan Cardon. Note that numerous additional interactomes have been predicted using computational methods (see section above). Epub 2020 Jul 22. [33] A network analysis can identify drug targets and biomarkers of diseases.[34]. Highly connected nodes (proteins) are called hubs. As described above, PPIs and thus whole interactomes can be predicted.  |  Lum et al. Though interactomes may be described as biological networks, they should not be confused with other networks such as neural networks or food webs. Recent proteome-wide analyses of RBDs have discovered that hundreds of proteins in the human proteome interact with RNA via intrinsically disordered regions (IDRs), which are protein regions lacking 3D structure in their native state [11,12]. Network properties include the degree distribution, clustering coefficients, betweenness centrality, and many others. Some of the main characteristics are as follows. that of Bacillus licheniformis. the technique determines which interactions are found. The interactome network was generated by Cytoscape software (https://cytoscape.org/). Here we present a database MitProNet which provides a comprehensive knowledgebase for mitochondrial proteome, interactome and human diseases. To characterize the impact of Hsp90 on the proteome and define the Hsp90 interactome, we used a combination of targeted affinity purification-mass spectrometry (AP-MS) and whole-cell quantitative proteomic approaches to identify proteins that interact with Hsp90 and depend on Hsp90 for stability. 2033-2051, CS1 maint: multiple names: authors list (, Learn how and when to remove this template message, Novel interactomics approach identifies ABCA1 as direct target of evodiamine, which increases macrophage cholesterol efflux, "APID interactomes: providing proteome-based interactomes with controlled quality for multiple species and derived networks", "The DISC1 pathway modulates expression of neurodevelopmental, synaptogenic and sensory perception genes", "Grasping at molecular interactions and genetic networks in Drosophila melanogaster using FlyNets, an Internet database", "Interactomic and pharmacological insights on human Sirt-1", "Estimating the size of the human interactome", "Protein stickiness, rather than number of functional protein-protein interactions, predicts expression noise and plasticity in yeast", "Neuron-specific protein interactions of Drosophila CASK-ß are revealed by mass spectrometry", "Benchmarking yeast two-hybrid systems using the interactions of bacterial motility proteins", "Create and assess protein networks through molecular characteristics of individual proteins", "Schizophrenia interactome with 504 novel protein–protein interactions", "Protein–Protein Interactions More Conserved within Species than across Species", "Prediction and characterization of protein–protein interaction network in Bacillus licheniformis WX-02", "Protinfo PPC: A web server for atomic level prediction of protein complexes", "Large-scale mapping of human protein interactome using structural complexes", "BIOVERSE: Enhancements to the framework for structural, functional, and contextual annotations of proteins and proteomes", "IBIS (Inferred Biomolecular Interaction Server) reports, predicts and integrates multiple types of conserved interactions for proteins", "Sequence co-evolution gives 3D contacts and structures of protein complexes", "Evolutionary profiles improve protein-protein interaction prediction from sequence", "Short Co-occurring Polypeptide Regions Can Predict Global Protein Interaction Maps", "Short co-occurring polypeptide regions can predict global protein interaction maps", "Systematic prediction of human membrane receptor interactions", "Evaluation of different biological data and computational classification methods for use in protein interaction prediction", "Functional annotation from predicted protein interaction networks", "Studying protein complexes by the yeast two-hybrid system", "Exploring the human diseasome: The human disease network", "Network medicine: A network-based approach to human disease", "VirHostNet: a knowledge base for the management and the analysis of proteome-wide virus-host interaction networks", "The protein interaction map of bacteriophage lambda", "Genome annotation and intraviral interactome for the, "Improving the yeast two-hybrid system with permutated fusions proteins: the Varicella Zoster Virus interactome", "Evolutionarily conserved herpesviral protein interaction networks", "The intra viral protein interaction network of hepatitis C virus", "Hepatitis C Virus Protein Interaction Network Analysis Based on Hepatocellular Carcinoma", "The Hepatitis E virus intraviral interactome", "A Second-generation Protein-Protein Interaction Network of Helicobacter pylori", "A proteome-wide protein interaction map for Campylobacter jejuni", "The Binary Protein Interactome of Treponema pallidum – the Syphilis Spirochete", "Global functional atlas of Escherichia coli encompassing previously uncharacterized proteins", "The binary protein-protein interaction landscape of Escherichia coli", "A Large Scale Analysis of Protein-Protein Interactions in the Nitrogen-fixing Bacterium Mesorhizobium loti", "A Large-scale Protein protein Interaction Analysis in Synechocystis sp. 1,2,* and . One characteristic of such distributions is that there are many proteins with few interactions and few proteins that have many interactions, the latter being called "hubs".
