metalife interaction viewer is a database for protein-protein interactions. the information is gathered from genome-wide experiments, text extraction from the article abstracts, and protein databases' text fields. because of the variety of sources used, the presented data cover the textbook information and the latest experimentally detected interactions. at present, the database holds 37500 proteins, which are involved in over 87000 interactions. the reliability of the text-extracted interactions could be significantly improved by the usage of recently developed scoring system.
according to the type of interaction, the interactions are categorized to direct, complex, functional and genetic. the interactions have a brief description and reference to the original article where they had been reported. the application offers a tool for revealing of possible pathways by looking for a route between distant interacting partners. besides in HTML, the results could be downloaded in XLS and TXT formats and the interaction network could be visualized via FLASH based viewer. there the proteins are shown in their actual subcellular locations and it allows fast expansion of the interaction network and results filtering.
as the interaction viewer is connected with the rest metalife products, additional textual annotations and physico-chemical properties of the proteins and their coding genes are available.
