PAC1, PAC1R, PACAPR, PACAPRI, Pituitary adenylate cyclase-activating polypeptide type I receptor, PACAP type I receptor, PACAP-R-1, PACAP-R1, ADCYAP1R1
This is a receptor for PACAP-27 and PACAP-38. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. May regulate the release of adrenocorticotropin, luteinizing hormone, growth hormone, prolactin, epinephrine, and catecholamine. May play a role in spermatogenesis and sperm motility. Causes smooth muscle relaxation and secretion in the gastrointestinal tract.
