WebThe mechanism by which FTIs work is through inhibition of this enzyme, which adds a fatty acid molecule to proteins (such as the oncogene, or cancer-generating, ras). Many proteins can exist in a cell in various locations, and the addition of a farnesyl group targets proteins to the plasma membrane. WebIn certain cancers, the GTPase activity of the RAS G-protein is inhibited. This means that the RAS protein can no longer hydrolyze GTP into GDP. What effect would this have on downstream cellular events? a. Cells will not proliferate. b. ERK is permanently inactivated. c. Regulated cell division. d. Uncontrolled cell proliferation. av382064 スイッチ
