The protein encoded by this gene is a member of theG protein-coupled receptor family 2. This protein is a receptor forparathyroid 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.[5]
The molecular interaction of the PTH2 receptor with thepeptideTIP39 has been characterized in full 3D molecular detail, identifying among other residues Tyr-318 intransmembrane helix 5 as a key residue for high affinity binding.[6]
