The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. [[http://www.uniprot.org/uniprot/PACA_HUMAN PACA_HUMAN]] Binding to its receptor activates G proteins and stimulates adenylate cyclase in pituitary cells.<ref>PMID:11175907</ref> [[http://www.uniprot.org/uniprot/GBB1_RAT GBB1_RAT]] Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. [[http://www.uniprot.org/uniprot/PACR_HUMAN PACR_HUMAN]] 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. | ||
