This page allows you to search for Gene Ontology (biological process, molecular function, cellular component) and KEGG pathways*, and find all the genes associated with each term.
* Note that KEGG FTP database is no longer free for academics. Our database is populated with the ontology as available openly via the API before July 2011. There will be no updates to this information. If you wish to use an updated version of the KEGG ontology you must license it and download it.
