Oxytocin causes contraction of the smooth muscle of the uterus and of the mammary gland. Acts by binding to oxytocin receptor (OXTR) (PubMed:18174156). Publication Abstract from PubMed Oxytocin is a neuropeptide that binds copper ions in nature. The structure of oxytocin in interaction with Cu(2+) was determined here by NMR, showing which atoms of the peptide are involved in binding. Paramagnetic relaxation enhancement NMR analyses indicated a binding mechanism where the amino terminus was required for binding and subsequently Tyr2, Ile3 and Gln4 bound in that order. The aromatic ring of Tyr2 formed a pi-cation interaction with Cu(2+). Oxytocin copper complex structure revealed by paramagnetic relaxation enhancement NMR analyses.
