Effects of statins and farnesyltransferase inhibitors on the

Protein prenylation involves the transfer of either a farnesyl or a geranylgeranyl moiety to C-terminal cysteine(s) of the target protein. There are three enzymes that carry out prenylation in the cell, farnesyl transferase, Caax protease and geranylgeranyl transferase I. Farnesylation is a type of prenylation, a post-translational modification of proteins by which an isoprenyl group is added to a cysteine residue. It is an important process to mediate protein–pro… WebMay 9, 2010 · Farnesyltransferase inhibitors (FTI) are small molecules that inhibit prenylation of multiple proteins, including Ras, RhoB, lamin A/C, and the centromere proteins (CENP-E and CENP-F; refs. 1, 7, 8).
