[Bioperl-l] getting proteins matching GO

[Davis, Sean (NIH/NHGRI)]

If I'm not mistaken, the GO database contains mappings from GOA
(http://www.ebi.ac.uk/GOA/).

Pedro,
You may want to check Bio::Ontology and especially Bio::OntologyIO. 
These are pretty cool modules, but you will have to install bioperl-live

or wait for bioperl 1.5 (which as I understand should be released soon).

You will have to download the GO DB locally and parse it with 
Bio::OntologyIO, I am not sure if somebody is working on remote access 
(not familiar if it is possible at the moment). By the way if you are 
not familiar with mysql and you are OK with perl, Bio::OntologyIO might 
be easiest for you. It will also include anything you are able to get 
from GO website. But you will have to keep local database (or flat 
file). Hope this helps.
Stefan
