Human AVPR1A

Figure. Concentration-dependent activation of AVPR1A by [R]‐vasopressin

Reporter cells were transfected with either the expression plasmid for human arginine vasopressin receptor 1A (AVPR1A) or the mock plasmid and treated with various concentrations of [R]‐vasopressin. Data points shown are the mean ± SEM of an experiment (n = 3), and the curve is a fit to Hill equation with an EC50 of 510 pM.

Vasopressin and oxytocin receptors

Vasopressin (AVP) and oxytocin (OT) receptors 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 [1].
