Identification
HMDB Protein ID HMDBP13665
Secondary Accession Numbers None
Name Ovarian cancer G-protein coupled receptor 1
Synonyms
  1. OGR-1
  2. G-protein coupled receptor 68
  3. GPR12A
  4. Sphingosylphosphorylcholine receptor
Gene Name GPR68
Protein Type Unknown
Biological Properties
General Function Not Available
Specific 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. Also functions as a metastasis suppressor gene in prostate cancer (By similarity).
