About IMEx data

IMEx is a consortium that provides curated molecular interaction data. Its homepage describes a non-redundant set of physical molecular interaction data from a broad taxonomic range of organisms. Records are curated from direct submissions, peer-reviewed journals, or pre-prints to a consistent standard. The data is provided by a network of participating public domain databases, including DIP, IntAct, MINT, and others listed on the site.

As of 3 June 2024, the homepage states that more than 1.5 million molecular interactions were available for search and download from the IMEx website and from Consortium member websites. Curation covers binding sites and the effect of point mutations on interactions. Contextual details such as cell lines and agonist or antagonist treatments are included when available. Pricing is not stated in the source, and the project is not listed as open source.
