Inhibitori disocijacije guanozin nukleotida
Inhibitori disocijacije guanozin nukleotida (engl. Guanosine nucleotide dissociation inhibitors - GDI) se vezuju za GDP-vezani oblik malih GTPaza Rho i Rab.[1][2][3] Oni ne samo da sprečavaju razmenu (odražavaju male GTPaze u neaktivnom stanju), nego isto tako sprečavaju i lokalizaciju malih GTPaza na membrani, koja je njihovo mesto dejstva. Ova inhibicija može biti sprečena dejstvom faktora razmene guanin nukleotida (GEF).
