We investigated the mechanisms that regulate the efficacy of agonists in the arginine-vasopressin (AVP)/oxytocin (OT) receptor system. In this paper, we present evidence that AVP, a full agonist of the vasopressin receptors, acts as a partial agonist on the oxytocin

The aim of the study was to computer-dock selected ligands to neurophyseal receptors in order to identify amino acid residues responsible for ligand-receptor interactions. To this aim, reliable oxytocin receptor (OTR) and arginine-vasopressin receptor (V1aR/V2R) models were built. The OTR-selective

Oxytocin receptors in rat hippocampal synaptic plasma membranes were compared with mammary gland and uterine oxytocin receptors. For this purpose, a highly specific oxytocic agonist [Thr4,Gly7]oxytocin was tritiated. We demonstrated that this ligand labels oxytocin receptors selectively. Scatchard analyses revealed
