Parathyroid hormone 2 receptor
An Error has occurred retrieving Wikidata item for infobox Parathyroid hormone 2 receptor is a protein that in humans is encoded by the PTH2R gene.[1]
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). This receptor is more selective in ligand recognition and has a more specific tissue distribution compared to parathyroid hormone 1 receptor (PTH1R). It is activated by PTH but not by parathyroid hormone-like hormone (PTHLH) and is particularly abundant in the brain and pancreas.[1] The molecular interaction of the PTH2 receptor with the peptide 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.[2]
Mechanism
It is a member of the secretin family of G protein-coupled receptors. The activity of this receptor is mediated by Gs protein, which activates adenylyl cyclase.[3]
