Parathyroid hormone 2 receptor is a protein that in humans is encoded by the PTH2R gene.

Function

The protein encoded by this gene is a member of the G protein-coupled receptor family 2. This protein is a receptor for parathyroid hormone (PTH) and parathyroid hormone 2 (PTH2). PTH2R is more selective in ligand recognition than the parathyroid hormone 1 receptor, and in particular is not activated by parathyroid hormone-related protein (PTHrP). It also has a more specific tissue distribution, and is particularly abundant in the brain and pancreas.

The molecular interaction of PTH2R with the peptide PTH2 (previously TIP39) has been characterized in full 3D molecular detail, identifying among other residues Tyr-318 in transmembrane helix 5 as a key residue for high affinity binding.

Mechanism

It is a member of the secretin family of G protein-coupled receptors. The activity of this receptor is mediated by G_s protein, which activates adenylyl cyclase.
