AngiotensinIIreceptortype2orAT2 isoneofthereceptorsthatbindtheoctapeptidehormoneAngiotensinII(AngII).
AngIIisthepeptidehormonethatgeneratesmostoftheknowneffectsoftherenin-angiotensinsystem(RAS).AngIIisgeneratedfromtheangiotensinogenproteinbytheactionsofrenin,angiotensinconvertingenzyme(ACE)andotherpeptidases.AngIIhasacentralroleincardiovascularhomeostasisbyregulatingvasoconstriction,renalNa+ andwaterreadsorption.Inaddition,AngIIinducescellgrowthandproliferationandhaspro-inflammatoryeffects.
MostofthephysiologicalactionsofAngIIaremediatedbyAT1 amemberofthe7-transmembranedomain,Gprotein-coupledreceptor(GPCR)superfamily.AT2 isalsoaGPCR,and islargelybelievedtohavecounter-regulatoryrolestotheonesexertedthroughtheAT1 receptor.Hence,bindingofAngIItotheAT2 receptorwillresultingrowtharrestandapoptosis,vasodilatationandhypotension.
AlthoughtheAT2 receptorisstructurallyamemberoftheGPCRsuperfamily,thesignalingmechanismselicitedfollowingAT2 receptoractivationarenotfullyclarified.RecentevidenceindicatesthattheAT2 receptorsignalsthroughtheGiα2 andtheGiα3 proteinsandthroughtheactivationofphosphotyrosinephosphatasessuchas SHP-1.
