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.[1]
parathyroid hormone 1 receptor (PTH1R) is the classical PTH receptor, is expressed in high levels in bone and kidney and regulates calciumionhomeostasis through activation of adenylate cyclase and phospholipase C.[2][3]
parathyroid hormone 2 receptor (PTH2R) is expressed primarily in the central nervous system, pancreas, testis, and placenta.[4]
