Figure 2 Kirsten rat sarcoma virus activation. Kirsten rat sarcoma virus is activated when guanine nucleotide exchange factor displaces guanosine diphosphate from nucleotide binding site allowing guanosine triphosphate (GTP) binding and inactivated upon GTP hydrolysis by intrinsic GTP-bound regulatory protein phosphatases (GTPase) activity enhanced by GTPase activating protein. GTP: Guanosine triphosphate; GAP: GTPase activating protein; GDP: Guanosine diphosphate; GEF: Guanine nucleotide exchange factor; KRAS: Kirsten rat sarcoma virus.
