Plays a role as a potent and selective agonist of PTH2R resulting in adenyl cyclase activation and intracellular calcium levels elevation. Induces protein kinase C beta activation, recruitment of beta-arrestin and PTH2R internalization. May inhibit cell proliferation via its action on PTH2R activation. Neuropeptide which may also have a role in spermatogenesis. May activate nociceptors and nociceptive circuits.
Subcellular locations: Secreted
Highly expressed in fetal and adult brain, cerebellum and trachea. Weakly expressed in spinal cord, fetal liver, kidney and heart.
