Regulator G proteinske signalizacije 14 (RGS14) je protein koji kod ljudi reguliše G proteinsku signalizaciju. On je kodiran RGS14 genom.[1]
Funkcija
RGS14 je član familije regulatora G proteinske signalizacije. Ovaj protein sadrži jedan RGS domen, dva Raf-slična Ras-vezujuća domena (RBD), i jedan GoLoco motiv. On prigušuje signalnu aktivnost G-proteina. RGS14 se vezuje svojim GoLoco domenom, za specifične tipove aktiviranih GTP-vezanih G alfa podjedinica. Delujući kao GTPaza i aktivirajući protein (GAP), on povećava brzinu GTP konverzije u GDP. Ova hidroliza omogućava G alfa podjedinicama da se vežu za G beta/gama podjedinicu heterodimera, formirajući neaktivne G-proteinske heterotrimere, čime se zaustavlja signal. Alternativne transkriptne splajsne varijante ovog gena su poznate, ali su nedovoljno karakterisane.[1]
Povišeno izražavanje RGS14 proteina u V2 sekundarnom vizuelnom korteksu miševa promoviše konverziju kratkotrajne u dugotrajnu memoriju prepoznavanja objekata.[2] RGS14 je prirodni supresor sinaptičke plastičnosti CA2 neurona i na hipokampusu baziranog učenja i memorije.[3]
