Receptor lizofosfatidne kiseline 2 (LPA₂) je protein koji je kod ljudi kodiran LPAR2 genom.^[1]^[2]^[3] LPA₂ je G protein spregnuti receptor za koji se vezuje lipidni signalni molekul lizofosfatidna kiselina (LPA).^[4]

Funkcija

Ovaj protein je član familije I G protein spregnutih receptora, kao i EDG familije. Ovaj protein funkcioniše kao receptor lizofosfatidne kiseline i doprinosi mobilizaciji Ca²⁺. To je kritični ćelijski respons na LPA, putem asocijacije sa Gi i Gq proteinima.^[1]

Interakcije

LPAR2 formira interakcije sa TRIP6.^[5]
