This gene encodes a precursor protein that is processed to produce oxytocin and neurophysin I. Oxytocin is a posterior pituitary hormone which is synthesized as an inactive precursor in the hypothalamus along with its carrier protein neurophysin I. Together with neurophysin, it is packaged into neurosecretory vesicles and transported axonally to the nerve endings in the neurohypophysis, where it is either stored or secreted into the bloodstream. The precursor seems to be activated while it is being transported along the axon to the posterior pituitary. This hormone contracts smooth muscle during parturition and lactation. It is also involved in cognition, tolerance, adaptation and complex sexual and maternal behaviour, as well as in the regulation of water excretion and cardiovascular functions.

GeneCards Summary for OXT Gene
OXT (Oxytocin/Neurophysin I Prepropeptide) is a Protein Coding gene. Diseases associated with OXT include epignathus and persistent genital arousal disorder. Among its related pathways are Signaling by GPCR and Interleukin receptor SHC signaling. GO annotations related to this gene include neurohypophyseal hormone activity and oxytocin receptor binding. An important paralog of this gene is AVP.
UniProtKB/Swiss-Prot for OXT Gene
Neurophysin 1 specifically binds oxytocin
Oxytocin causes contraction of the smooth muscle of the uterus and of the mammary gland
Oxytocin receptors (OT) are G-protein-coupled receptors that mediate parturition and lactation. They are closely related to vasopressin receptors. Oxytocin receptors are coupled to Gq/11 proteins and are localized to the myoepithelial cells of the mammary gland.
