Vasopressin and oxytocin receptors in GtoPdb v.2023.1

This is the authors' abstract. We don't add key points for this paper.

Vasopressin (AVP) and oxytocin (OT) receptors (nomenclature as recommended by NC-IUPHAR [94]) are activated by the endogenous cyclic nonapeptides vasopressin and oxytocin. These peptides are derived from precursors which also produce neurophysins (neurophysin I for oxytocin; neurophysin II for vasopressin). Vasopressin and oxytocin differ at only 2 amino acids (positions 3 and 8). There are metabolites of these neuropeptides that may be biologically active [69].
