WebTo mediate the process of shuttling between the active and inactive forms, GTPases need the help of two families of proteins: GTPase-activating proteins (GAPs) and guanine nucleotide exchange factors (GEFs). GEFs replace the GDP bound to inactive GTPase with GTP, making the enzyme active and transducing a wide variety of cellular signals.
