OXT, or oxytocin, induces physiological effects by binding to neurophysin 1 and interacting with the oxytocin receptor (OXTR). This interaction results in smooth muscle contraction in the uterus and mammary gland, crucial for labor and breastfeeding, respectively, by modulating OXTR activity. OXT Protein, Human (P.pastoris, His) is the recombinant human-derived OXT protein, expressed by P. pastoris , with N-6*His labeled tag. The total length of OXT Protein, Human (P.pastoris, His) is 94 a.a., with molecular weight of ~16 kDa.
