Farnesyltransferase
From Proteopedia
Farnesyltransferase (FTase) is part of the prenyltransferase group. FTase modifies proteins by adding farnesyl diphosphate (FPP) – an isoprenoid lipid – to a cysteine 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. Thus, FTase inhibitors are being tested as anti-cancer agents. FTase are composed of 2 subunits. The β subunit coordinates a Zn atom.
