A comprehensive protein-centric ID mapping service for molecular data integration.

Motivation: Identifier (ID) mapping establishes links between various biological databases and is an essential first step for molecular data integration and functional annotation. ID mapping allows diverse molecular data on genes and proteins to be combined and mapped to functional pathways and ontologies. We have developed comprehensive protein-centric ID mapping services providing mappings for 90 IDs derived from databases on genes, proteins, pathways, diseases, structures, protein families, protein interaction, literature, ontologies, etc. The services are widely used and have been regularly updated since 2006.Availability: www.uniprot.org/mappingandproteininformation-resource.org/pirwww/search/idmapping.shtmlContact: huang@dbi.udel.edu [ABSTRACT FROM AUTHOR]
