Hipofizni adenilat ciklazno aktivirajući peptid (PACAP) je protein koji je kod ljudi kodiran ADCYAP1 genom.[1][2] PACAP je sličan sa vazoaktivnim intestinalnim peptidom. Jedan od njegovih efekata je stimulacija enterohromafinu sličnih ćelija. On se vezuje za receptor vazoaktivnog intestinalnog peptida.

Funkcija[uredi - уреди]

Posredstvom hipofiznog adenilat ciklazno aktivirajućeg polipeptidnog receptor tipa I|, ovaj polipeptid stimuliše adenilat ciklazu i naknadno povišava nivoe cAMP u ciljnim ćelijama. Adenilat ciklazno aktivirajući peptid 1 nije samo hipofiziotropni hormon, nego takođe funkcioniše kao neurotransmiter i neuromodulator. Osim toga on učestvuje u parakrinoj i autokrinoj regulacije pojedinih tipova ćelija. Ovaj gen se sastoji of pet eksona. Eksoni 1 i 2 kodiraju 5' UTR i signalni peptid, respektivno; ekson 4 kodira peptid srodan adenilat ciklazno aktivirajućem polipeptidu; i ekson 5 kodira maturisani peptid i 3' UTR. Ovaj gen kodira tri različita peptida, uključujući dva izotipa: kratku i dugačku formu.[2]

Interakcije[uredi - уреди]

Hipofizni adenilat ciklazno aktivirajući peptid formira interakcije sa sektretinskim receptorom.[3]
