Receptor for parathyroid hormone and for parathyroid hormone-related peptide. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and also a phosphatidylinositol-calcium second messenger system. Interacts (via N-terminal extracellular domain) with PTHLH and PTH (PubMed:1658941). Homodimer in the absence of bound ligand. Peptide hormone binding leads to dissociation of the homodimer (By similarity). N-glycosylated. Belongs to the G-protein coupled receptor 2 family.
