Pituitary adenylate cyclase-activating polypeptide type I receptor (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.
