What is the best way to obtain the GO annotations for a list of UniProt Accession Numbers in batch?
With UniProt accession numbers, you can obtain all GO annotations by parsing a GOA gene association file, which are provided in a simple 15 column tab-delimited format. These files are available from our ftp site, at ftp://ftp.ebi.ac.uk/pub/databases/GO/goa/ The GOA project offers users a number of different files at this site so people can choose whether to look at the entire collection of GO annotations to proteins in UniProtKB: ftp://ftp.ebi.ac.uk/pub/databases/GO/goa/UNIPROT/gene_association.go_uniprot.gz Or, if you were only interested in proteins from a particular species, we also provide non-redundant, species-specific files for human, mouse, rat, zebrafish, chicken, cow and Arabidopsis proteins (these files are created using the International Protein Index (IPI) – which provides a top level guide to the main databases that describe the proteomes of higher eukaryotic organisms) : ftp://ftp.ebi.ac.uk/pub/databases/GO/goa/HUMAN/gene_association.goa_human.gz Further information on
