General annotation (Comments)

Function	This is a specific receptor for parathyroid hormone. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. PTH2R may be responsible for PTH effects in a number of physiological systems. It may play a significant role in pancreatic function. PTH2R presence in neurons indicates that it may function as a neurotransmitter receptor.
Subunit structure	Binds to TIPF39/TIP39 By similarity.
Subcellular location	Cell membrane; Multi-pass membrane protein.
Tissue specificity	Abundantly expressed in brain, arterial and cardiac endothelium. Found as well in sperm, in the head of the epididymis. Lower expression is found in vascular smooth muscle, exocrine pancreas, testis and placenta.
Sequence similarities	Belongs to the G-protein coupled receptor 2 family.
