Model illustrating the potential role of CD157 in oxytocin release. CD157 catalyzes NAD+ hydrolysis and synthesis of cADPR, then cADPR acts at Ryanodine receptors expressed in intracellular Ca2+ stores to initiate [Ca2+]irelease to cytosole. As a result, OXT is secreted from the cell into the blood and brain tissue. ADPR, ADP-ribose; cADPR, cyclic ADP-ribose; OXT, oxytocin.
