ID Mapping

QuickGO maps between different identifier types by using a combination of mapping files provided by the databases, and using identifier cross-references supplied by UniProtKB.

If more than one identifier type needs to be used to map all required sequences, drag the selected databases to change the order in which identifiers are found.
