The Gene Ontology (GO)1 provides a controlled vocabulary to describe attributes of gene products. GO contains three ontologies that describe the molecular functions, biological processes, and cellular components of proteins.


Molecular Function

The human ontology contains 2,800 terms, 14,401 genes, and 43,207 associations.

The mouse ontology contains 2,380 terms, 13,932 genes, and 47,595 associations.

Biological Process

The human ontology contains 5,215 terms, 13,293 genes, and 47,287 associations.

The mouse ontology contains 4,539 terms, 12,805 genes, and 45,480 associations.

Cellular Component

The human ontology contains 834 terms, 15,210 genes, and 39,984 associations.

The mouse ontology contains 686 terms, 14,548 genes, and 34,827 associations.


All data for this ontology was downloaded on March 5, 2009 for human and March 23, 2009 for mouse.
