Angiotenzinski II receptor tip 2, (AT₂ receptor) je protein koji je kod ljudi kodiran AGTR2 genom.^[1]

Funkcija

Angiotenzin II je potentan vazokonstrikcioni hormon i primarni regulator aldosteronske sekrecije. On je važan efektor kontrole krvnog pritiska i zapremine kardiovaskularnog sistema. On deluje kroz najmanje dva tipa receptora: AT₁ i AT₂. AGTR2 pripada familiji 1 G protein-spregnutih receptora. On je integralni membranski protein. On učestvuje u funkcijama centralnog nervnog i kardiovaskularnog sistema koje su posredovane renin-angiotenzinskim sistemom. Ovaj receptor posreduje programiranu ćelijsku smrt (apoptozu). Kod odraslih osoba, on je visoko izražen u miometrijumu sa niskim nivoima u nadbubrežnoj žlezdi i jajovodima. On je visoko izražen u fetalnim bubrezima i interstinalnom sistemu. Humani AGTR2 gen se sastoji od sastoji od tri eksona na rasponu od najmanje 5 kb.^[1]

Stimulacija AT₂ receptora selektivnim agonistom CGP 42112A povećava proizvodnju azot-monoksida sluzokože.^[2]

Interakcije

Za angiotenzinski II receptor tip 2 je pokazano da interaguje sa MTUS1.^[3]
