[Obo-discuss] Major update to the Protein Ontology (PRO)

[Darren N. <da...@ge...>]

The PRO Consortium announces the latest release of the Protein Ontology 
(PRO) which features a vastly expanded coverage of proteins at the 
species-non-specific gene level (see figure on the PRO home page 
http://pir.georgetown.edu/pro/ and question four on the Q&A page 
http://pir.georgetown.edu/pro/PRO_Q&A.pdf for definition).  Currently 
the majority of these added terms are directly under the root node 
"protein," giving the ontology a flattened look.  Building an 
intermediate family level is ongoing.

Some stats:
18238 PRO terms
    1093 terms are in the 'modification' category.
    941 terms are in the 'sequence' category.
    15933 terms are in the 'gene' category.        <--- was ~1200
    260 terms are in the 'family' category.
1233 terms are annotated, codifying the information from 842 papers.
   1781 connections to GO (599 PRO terms).
   235 connections to MOD (194 PRO terms).
   599 connections to Pfam (358 PRO terms).
   325 connections to SO (307 PRO terms).
   296 annotations of a phenotype (289 PRO terms).
