iRefIndex is a resource based on peptide sequence matching, providing an index of protein interactions available in a number of primary interaction databases (including BIND, BAR, BioGRID, CORUM, DIP, InnateDB, IntAct, HPRD, HuRi, MATRIXDB, MPACT, MPPI and MPIDB, REACTOME, VIRUSHOST, UNIPROTPP, HPIDB, BHF-UCL, and QuickGO). This index allows the user to search for a protein and retrieve a non-redundant list of interactors for that protein. Hence, iRefIndex represents a unifying index that facilitates searching for these data whilst grouping together redundant interaction data and recording the methods used to perform this grouping. This method allows users to integrate their own data with the iRefIndex in a way that ensures proteins with the exact same sequence will be represented only once.

This tool, originally developed by Ian Donaldson, is maintained by VIB Technologies.
