UTEP GPCR-PEnDB

The database contains more than 3000 confirmed GPCR (CG) and 3500 non-GPCR (CN) from more than 1200 different organisms including bacteria and viruses. About half of the non-GPCR sequences are transmembrane proteins (CNT). It also incorporates predicted GPCRs (PG) from three organisms. Each protein, with a unique identification number, is linked to its source organism, gene name, protein name, sequence length, and other features such as amino acid and dipeptide compositions. For the GPCRs, the lengths of characteristic structural regions (i.e., N-terminal, C-terminal, seven transmembrane helices, and the extracellular and intracellular loops) are provided. If available, GPCR family classification information is also included.
