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


GOlr is the Solr index used by AmiGO. It has been adopted as the faceted search index for Monarch


The primary AmiGO developer is Seth Carbon
