 == Function ==
-'''Geranylgeranyl transferase''' type 1 (GGT1) adds a 20-carbon isoprenoid group called geranylgeranyl (GG) to the C-terminal of proteins containg the CAAX motif (Cysteine, Aliphatic, Aliphatic, any amino acid).  '''Geranylgeranyl transferase type 2''' (GGT2) adds 2 GG groups to C-terminal cysteine residue of a protein.  The addition of the hydrophobic prenyl group causes the proteins to become membrane-associated<ref>PMID:16477080</ref>.
