The human protein, encoded by the gene OR51E2, is a member of the G-protein coupled receptor 1 family. The protein's cellular localization is indicated to be membrane-associated. Additional synonyms or past names for this protein may include: HPRAJ, OR51E3P, OR52A2, PSGR. Homology is conserved in other species, such as Mouse, Rat.
