GPR68
G-Proteins

DEFINITION

G protein coupled receptor 68,with strong homology to GPR4,expressed in spleen,testis,small intestine,peripheral blood leucocytes,brain,heart,lung,placenta,kidney GPR68
UniProtKB/Swiss-Prot Function:
Proton-sensing receptor involved in pH homeostasis. May represents an osteoblastic pH sensor regulating cell-mediated responses to acidosis in bone. Mediates its action by association with G proteins that stimulates inositol phosphate (IP) production or Ca(2+) mobilization. The receptor is almost silent at pH 7.8 but fully activated at pH 6.8. Function also as a metastasis suppressor gene in prostate cancer (By similarity). OGR1_HUMAN,Q15743
