Farnesyltransferase posttranslationally-modifies proteins by adding an isoprenoid lipid called a farnesyl group to the -SH of the cysteine near the end of target proteins to form a thioether linkage. This process, called farnesylation (which is a type of prenylation), causes farnesylated proteins to become membrane-associated due to the hydrophobic nature of the farnesyl group. Most farnesylated proteins are involved in cellular signaling wherein membrane association is critical f… WebbPrenylation is a class of lipid modification involving covalent addition of either farnesyl (15-carbon) or geranylgeranyl (20-carbon) isoprenoids to conserved cysteine residues at or …
