TIP39

Tuberoinfundibular peptide of 39 residues is a protein that in humans is encoded by the PTH2 gene.[1][2]

TIP39 is related to parathyroid hormone (PTH; MIM 168450) and PTH-related protein (PTHRP; MIM 168470) and is a ligand for PTH receptor-2 (PTHR2; MIM 601469) (John et al., 2002).[supplied by OMIM][2]

The molecular interaction of TIP39 with the PTH2 receptor 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 [3]
