AmiGO is the official tool for searching and browsing the Gene Ontology database. It allows you to explore a controlled vocabulary of terms covering biological concepts, and a large number of genes or gene products whose attributes have been annotated using GO terms.

Using AmiGO, you can:

• Search for a gene or gene product, or a list of gene or gene products, and view the GO term associations
• Perform a sequence identity BLAST search and view the GO term associations for the genes or proteins returned
• Search for GO terms and view the genes or gene products they are annotated to
• Browse the GO ontology and view terms
