Regulator G proteinske signalizacije 17 (RGS17) je protein koji je kod čoveka kodiran RGS17 genom.[1][2]
Ovaj gen kodira člana regulatorne G-proteinske signalne familije. Ovaj protein sadrži konzervirani motiv od 120 aminokiselina koji se naziva RGS domen, i cisteinom bogati region. On prigušuje signalnu aktivnost G-proteina vezivanjem za aktiviranu, GTP-vezanu G alfa podjedinicu i delujući kao aktivirajući protein GTPaze (GAP), čime povišava brzinu GTP konverzije do GDP-a. Ova hidroliza omogućava G alfa podjedinicama da se vežu za G beta/gama heterodimere, formirajući neaktivne G-proteinske heterotrimere, čime se zaustavlja signal.[2] Zajedno sa RGS4, RGS9 i RGS14,[3][4] RGS17 učestvuje u terminaciji signalizacije mi opioidnog receptora i razvoju tolerancije na opioidne analgetike.[5][6]
