Vasopressin

Vasopressin and vasotocin receptors studied, critical amino acids identified

Published in Cancer Weekly, March 1st, 2005

Recent research from South Korea published in the Journal of Biological Chemistry has reported on the identification of amino acid residues that direct differential ligand selectivity for arginine forms of vasopressin and vasotocin.

"Arginine vasotocin (VT) is the ortholog in all nonmammalian vertebrates of arginine vasopressin (AVP) in mammals. We have previously cloned an amphibian V1a-type vasotocin receptor (VT1R) that exhibited higher sensitivity for VT than AVP, while the mammalian V1a type receptor (V1aR) responded better to AVP than VT.

"In the present study," reported S. Acharjee and colleagues, Chonnam National University, "we...
