Suppose you have a death certificate and gives the date of death. Suppose it does not give the date of birth but instead gives the age rather precisely -- so many years, so many months, and so many days. You would enter the date of death for the second event and the precise age for the elapsed time. The first event would then give the date of birth.
1 Oxytocin is a neuropeptide produced in the hypothalamus and secreted by the pituitary gland. 2  Oxytocin is released during sex, childbirth and lactation to aid reproductive functions. 3  This neuropeptide exerts multiple psychological effects, influencing social behavior and emotion.
Summary. The protein encoded by this gene belongs to the G-protein coupled receptor family and acts as a receptor for oxytocin. Its activity is mediated by G proteins which activate a phosphatidylinositol-calcium second messenger system.The oxytocin-oxytocin receptor system plays an important role in the uterus during parturition. The relations between OXTR and loneliness were examined, as well as interactions between OXTR and sex, parental support, 5-HTTLPR genotype, and DRD2 genotype. 2  Initial evidence that the capacity to respond to suggestions for altered internal experience (hypnosis) is influenced by the oxytocin receptor gene.
