The International Molecular Exchange Consortium (IMEx) [1] is a group of the major public providers of molecular interaction data to provide a single, non-redundant set of molecular interactions. Data is captured using a detailed curation model and made available in the PSI-MI standard formats. Participating databases include DIP, IntAct, [2] the Molecular Interaction Database (MINT), [3] MatrixDB, [4] InnateDB, IID, HPIDB, UCL Cardiovascular Gene Annotation, MBInfo, Molecular Connections and UniProt. [1] The group collates the interaction data and prevents duplicate entries in the various databases. The IMEx consortium also supports and contributes to the development of the HUPO-PSI-MI XML format, which is now widely implemented. [1] [5]
