Farnesyl transferase (FTase) is a zinc-dependent enzyme. It adds a 15-carbon isoprenoid called a farnesyl group to proteins bearing a CaaX motif. FTase regulates the activation of oncogenic Ras protein and consequently affects intracellular signal transduction, and cell proliferation. Ras-induced malignant transformation requires Ras farnesylation, a lipid posttranslational modification...
