Receptor vazoaktivnog intestinalnog peptida 2 (VPAC2) je G protein spregnuti receptor koji je kod ljudi kodiran VIPR2 genom.[1]

Tkivna distribucija

VIPR2 je Izražen u materici, prostati, glatkim mišićima gastrointestinalnog trakta, seminalnim vezikulama i koži, krvnim sudovima i grudnoj žlezdi.[2][3] VIPR2 je takođe izražen u malom mozgu.[4]

Funkcija

Vazoaktivni intestinalni peptid (VIP) i hipofizni adenilat ciklazno aktivirajući peptid (PACAP) su homologni peptidi koji funkcionišu kao neurotransmiteri i neuroendokrini hormoni. Mada su receptori za VIP (VIRP 1 i 2) i PACAP (ADCYAP1R1) homologni, oni se razlikuju u pogledu supstratnih specifičnositi i obrazaca izražavanja.[1] Prenos signal putem VIPR2 receptora dovodi do povećane aktivnosti adenilat ciklaze.[5] VIPR2 posreduje antiinflamatorne efekte VIP hormona.[6]

Istraživanja koristeći VPAC2 nokaut miševe indiciraju da ovaj receptor učestvuje u cirkadijalnom ritmu, rastu, potrošnji bazalne energije i muškoj reprodukciji.[7][8][9][10]

Aktivacija VIPR2 i/ili PAC1 receptora učestvuje u kožnoj aktivaciji vazodilatacije kod ljudi.[11]

Splajsne varijante mogu da modifikuju imunoregulatorne doprinose VIP-VIPR2 ose.[12]

Klinički značaj

VIPR2 moše da učestvuje u šizofreniji.[13]

Abnormalno izražavanje VIPR2 iRNK u tkivu žučne kese može da doprinese formiranju žučnog kamenja i polipa.[14]
