'''Farnesyltransferase''' (FTase) is part of the prenyltransferase group. FTase modifies proteins by adding farnesyl diphosphate (FPP) – an isoprenoid lipid – to a cysteine in a CAAX motif near the C terminal. This addition forms a thioether linkage, makes the protein more hydrophobic and associates it with the membrane. Farnesylated proteins – like those of the Ras family - are involved in cellular signaling<ref>PMID:15451670</ref>
