Funkcija
GTPaze funkcioniraju kao molekulni prekidači koji se mogu prebacivati između dva stanja: aktivno, kada je GTP vezan, i neaktivno, kada je vezan BDP. 'Aktivno' obično znači da molekula djeluje kao signal za pokretanje drugih događaja u ćeliji. Kad se vanćelijski ligand veže za G-protein spregnuti receptor, receptor mijenja svoju konformaciju i uključuje trimerne G-proteine, koji se povezuju s njim, izazivajući ih da izbace svoj BDP i zamijene ga GTP-om. Prekidač se isključuje kada G-protein hidrolizira svoj vezani GTP, pretvarajući ga nazad u BDP. No, prije nego što se to dogodi, aktivni protein ima priliku difundirati dalje od receptora i prenositi svoju poruku na duži period do svog nizvodnog cilja.[6]
