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).

Involvement in disease

Amelogenesis imperfecta, hypomaturation type, 2A6

AI2A6

A defect of enamel formation. The disorder involves both primary and secondary dentitions. The teeth have a shiny agar jelly appearance and the enamel is softer than normal. Brown pigment is present in middle layers of enamel.

None

The disease is caused by variants affecting the gene represented in this entry.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family.

Tissue specificity

Found at low level in a wide range of tissues, but significantly expressed in lung, kidney, bone and nervous system.

Cellular localization

  • Cell membrane
  • Multi-pass membrane protein
