Description:
A peptide that accumulated as the major product during the proteolysis of arginine vasopressin by rat brain synaptic membranes was isolated and its structure was shown to be the hexapeptide pGlu-Asn-Cys(Cys)-Pro-Arg-Gly-NH2. When administered intracerebroventricularly in extremely low doses, this vasopressin fragment and its desglycinamide derivative facilitated memory consolidation in a passive avoidance situation. These vasopressin metabolites, which are devoid of pressor activity, constitute highly potent neuropeptides with selective effects on memory and related processes; they are activated via proteolytic processing of vasopressin by brain peptidases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burbach, J P -- Kovacs, G L -- de Wied, D -- van Nispen, J W -- Greven, H M -- New York, N.Y. -- Science. 1983 Sep 23;221(4617):1310-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6351252" target="_blank"〉PubMed〈/a〉
