The InterPro  ontology contains data on protein domains, families, and functional sites. InterPro annotations give information about the function, structure, and evolution of the domains. It combines several other databases (PROSITE, PRINTS, Pfam, ProDom, SMART, TIGRFAMs, PIRSF, SUPERFAMILY, PANTHER and Gene3D).
Statistics can now be found in the footers of each table in the GREAT web output.
