Receptor lizofosfatidne kiseline 1 (LPA₁) je protein koji je kod ljudi kodiran LPAR1 genom.^[1]^[2]^[3] LPA₁ je G protein spregnuti receptor za koji se vezuje lipidni signalni molekul lizofosfatidna kiselina (LPA).^[4]

Funkcija

[uredi | uredi kod]

Integralni membranski protein kodiran ovim genom pripada grupi EDG receptora. Ti receptori su članovi familije G protein spregnutih receptora. EDG receptori posreduju različite bioločkie funkcije, uključujući proliferaciju, agregaciju trombocita, kontrakcije glatkih mišića, inhibiciju diferencijaciju neuroblastomnih ćelija, hemotaksu, i invaziju tumornih ćelija. Alternativno splajsovanje ovog gena je uočeno i dve transkriptne varijante su opisane. One kodiraju identične proteine.^[1]
