Regulator G-proteinske signalizacije 1 je protein koji je kod ljudi kodiran RGS1 genom.[1][2][3]

Ovaj gen kodira člana familje regulatora G-proteinske signalizacije. Ovaj protein je lociran na citosolnoj strani ćelijske membrane i sadrži konzervirani, 120 aminokiselina dug motiv koji se naziva RGS domen. On umanjuje signalnu aktivnost G-proteina putem vezivanja za aktivirane, GTP-vezane G alfa podjedinice, i tako što deluje kao GTPazni aktivirajući protein (GAP), povećanjem brzine konverzije GTP do GDP. Ova hidroliza omogućava alfa podjedinicama da se vežu za G beta/gama heterodimerne podjedinice, formiraju neaktivne G-proteinske heterotrimere, i time prekinu signal.[3]
