Technical Data
Farnesyltransferase (FPTA, CAAX Box, GGTase-I-alpha)
Prenylation is a common intracellular posttranslational protein modification catalyzed by prenyltransferases. The best characterized among these prenyltransferases is the CAAX farnesyl transferase (, which is alpha-beta heterodimeric enzyme. It catalyzes the attachment of a farnesyl group from farnesyl phosphate to cysteine residues at the fourth position from the C terminus of proteins that end in the CAAX box. FNTA or the alpha subunit of farnesyl transferase is shared by the geranyl-geranyl protein transferases. Apart from transfer of farnesyl and geranyl groups to proteins, FNTA has been proposed to regulate intracellular signaling pathways involving p21ras. Reports have shown that FNTA interacts with TGF-beta and activin-type I receptors.
