Regulator G-proteinske signalizacije 20 je protein koji je kod ljudi kodiran RGS20 genom.[1][2][3]

Regulatori G proteinske signalizacije (RGS) su regulatorne i strukturne komponente G protein-spregnutih receptorskih kompleksa. RGS proteini su GTPazni aktivatori za Gi (GNAI1; MIM 139310) i Gq (GNAQ; MIM 600998) klasu G-alfa proteina. Oni ubrzavaju tranzit kroz ciklus GTP vezivanja i hidrolize i tim putem ubrzavaju signalizacionu kinetiku i terminaciju.[3]

Interakcije

RGS20 formira interakcije sa GNAO1[4] i GNAZ.[1][5]
