Description:
A computational method is proposed for inferring protein interactions from genome sequences on the basis of the observation that some pairs of interacting proteins have homologs in another organism fused into a single protein chain. Searching sequences from many genomes revealed 6809 such putative protein-protein interactions in Escherichia coli and 45,502 in yeast. Many members of these pairs were confirmed as functionally related; computational filtering further enriches for interactions. Some proteins have links to several other proteins; these coupled links appear to represent functional interactions such as complexes or pathways. Experimentally confirmed interacting pairs are documented in a Database of Interacting Proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marcotte, E M -- Pellegrini, M -- Ng, H L -- Rice, D W -- Yeates, T O -- Eisenberg, D -- P01 GM 31299/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):751-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UCLA-Department of Energy Laboratory of Structural Biology and Molecular Medicine, University of California at Los Angeles, Los Angeles, CA 90095-1570, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10427000" target="_blank"〉PubMed〈/a〉
