There are two known parathyroid hormone receptors in mammals termed PTH1R and PTH2R. These receptors bind parathyroid hormone and are members of the GPCR family of transmembrane proteins.
- parathyroid hormone 1 receptor (PTH1R) is the classical PTH receptor, is expressed in high levels in bone and kidney and regulates calcium ion homeostasis through activation of adenylate cyclase and phospholipase C.
- parathyroid hormone 2 receptor (PTH2R) is expressed primarily in the central nervous system, pancreas, testis, and placenta.
