[Bioperl-l] getting proteins matching GO

[Stefan Kirov]

What organism? You can use either EnsMart (for example for human there 
is a table called hsapiens_gene_ensembl__xref_go__dm) or you can use 
GeneKeyDB if you install it locally (genereg.ornl.gov/gkdb), there is a 
table called ll_go, which you can search for the gene 
identifier(locuslink), associated with a particular GO term and then get 
the protein accession from another table  (something like : "select 
r.np_accn from ll_go g, ll_refseq_nm r where r.ll_id=g.ll_id and 
g.go_term=?") and fetch the seq from RefSeq, etc. Both Ensembl and 
GeneKeyDB are restricted to certain eukaryotes. So it all depends on 
what kind of organisms you are expected to work with.
