How can I get FASTA files of proteins annotated to a particular GO term?
On the GO web site, select the link to the AmiGO browser (which will allow you to search the GO gene associations contributed by all the participating databases) and enter your chosen GO term (e.g ‘mitochondrion’) in the Search box. Toggle the ‘Terms’ button and click on ‘Submit Query.’ The resulting page will present a list of all Gene Product Associations to the queried term and its children. Note that associations may be filtered according to Species, Data Source, and Evidence Code as well as to only those gene products annotated directly to the queried term. Check the genes you require the sequence for and, at the bottom of the page, toggle the option box to ‘Get FASTA sequences’. Hit the ‘Submit Query’ button. If you would like sequences for all of the gene products, click on the ‘Select all’ option.
