Summaries for GPR68 Gene

Entrez Gene Summary for GPR68 Gene

  • The protein encoded by this gene is a G protein-coupled receptor for sphingosylphosphorylcholine. The encoded protein is a proton-sensing receptor, inactive at pH 7.8 but active at pH 6.8. Mutations in this gene are a cause of amelogenesis imperfecta. [provided by RefSeq, Feb 2017]

GeneCards Summary for GPR68 Gene

GPR68 (G Protein-Coupled Receptor 68) is a Protein Coding gene. Diseases associated with GPR68 include Amelogenesis Imperfecta, Hypomaturation Type, Iia6 and Amelogenesis Imperfecta. Among its related pathways are Peptide ligand-binding receptors and Osteoclast Signaling. Gene Ontology (GO) annotations related to this gene include G-protein coupled receptor activity. An important paralog of this gene is GPR4.

UniProtKB/Swiss-Prot for GPR68 Gene

  • 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).
