How to convert NCBI gi or protein accession number to GO term?

Question

[huangjs2017]

I want to get GO annotation from protein accession number or gi in NCBI NR database, I find the mapping file from https://ftp.ncbi.nih.gov/gene/DATA/gene2go.gz. However, it only contains a few proteins' GO info. Where or How can I find complete GO annotation for proteins from NCBI NR?

Thanks!

Your question is lacking a good structure and example, so people will be limited on how much they can help you. With that being said, if you're simpling looking for GO terms associated with a given gene - without performing functional enrichment analysis - you can use biomart. Hope it helps!
