The Protein Ontology Consortium--Protein Information Resource, The Jackson Laboratory, Reactome, and the Department of Philosophy at the State University of New York at Buffalo--is pleased to announce PRO Release 25.0 (23-December-2011). PRO describes the relationships of proteins and protein evolutionary classes, delineates the multiple protein forms of a gene locus (ontology for protein forms), protein complexes, and interconnects existing ontologies. Further information is available at http://pir.georgetown.edu/pro/.
