pituitary adenylate cyclase-activating polypeptide type 1 receptor; PACAP type I receptor; PACAP-R-1 (ADCYAP1R1)
Function:
- receptor for PACAP-27 & PACAP-38.
- activity is mediated by G proteins which activate adenylyl cyclase
- may regulate the release of adrenocorticotropin, luteinizing hormone, growth hormone, prolactin, epinephrine, & other catecholamines
- may play a role in spermatogenesis & sperm motility
- causes smooth muscle relaxation & secretion in the gastrointestinal tract
Structure: belongs to the G-protein coupled receptor 2 family
Compartment: cell membrane; multi-pass membrane protein
Expression:
- most abundant in the brain
- low expression in the lung, liver, thymus, spleen, pancreas & placenta
