Accessive is a project designed to facilitate translation between the numerous formats of gene, transcript, and protein identifiers in common use in bioinformatics applications. Accessive is completely open-source and free to use and comes in three forms:
The Accessive database currently supports a small set of species judged to be of particular interest to the research community; custom databases for additional species can be constructed by request. The Accessive database is constructed using identifier mapping information from Ensembl, Uniprot, and Nextprot.
