The Binding Site of Neuropeptide Vasopressin V1a Receptor
Open accessAbstract
To identify receptor functional domains underlying binding of the neurohypophysial hormones vasopressin (AVP) and oxytocin (OT), we have constructed a three-dimensional (3D) model of the V1a vasopressin receptor subtype and docked the endogenous ligand AVP. To verify and to refine the 3D model, residues likely to be involved in agonist binding were selected for site-directed mutagenesis. Our experimental results suggest that AVP, which is characterized by a cyclic structure, could be completely buried into a 15-20-A deep cleft defined by the transmembrane helices of the receptor and interact with amino acids located within this region. Moreover, the AVP-binding site is situated in a position equivalent to that described for the cationic neurotransmitters. Since all mutated residues are highly conserved in AVP and OT receptors, we propose that the same agonist-binding site is shared by all members of this receptor family. In contrast, the affinity for the antagonists tested, including those with a structure closely related to AVP, is not affected by mutations. This indicates a different binding mode for agonists and antagonists in the vasopressin receptor.

In the citing paper
“Like the OTR, most of the critical sites for AVPV1aR binding are conserved (Barberis et al., 1998; Chini et al., 1995; Mouillac et al., 1995; Thibonnier et al., 2000), with one notable exception.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
