What is a mapping?

These files contain concepts from external database systems, such as Enzyme Commission numbers, UniProt keywords and TIGR roles, indexed to equivalent GO terms. The mappings are typically made manually; details can be found in the file headers.

Mappings should be used as a guide only.

Although we endeavour to make mappings as accurate as possible, we cannot guarantee that the mappings provided by the GO project are either complete or exact. This may be due to the absence of definitions from GO terms or from terms in some external systems; the GO ontologies and the external database may also have changed since the mapping was made. Please report any errors or suggest alternatives to the GO helpdesk.
