Protein attributes

Sequence length	379 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the transfer of a farnesyl or geranyl-geranyl moiety from farnesyl or geranyl-geranyl pyrophosphate to a cysteine at the fourth position from the C-terminus of several proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X. The alpha subunit is thought to participate in a stable complex with the substrate. The beta subunit binds the peptide substrate.
Catalytic activity	Farnesyl diphosphate + protein-cysteine = S-farnesyl protein + diphosphate. Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate.
Subunit structure	Heterodimer of an alpha and a beta subunit. Ref.12 Ref.13 Ref.14
Sequence similarities	Belongs to the protein prenyltransferase subunit alpha family. Contains 5 PFTA repeats.
