Protein attributes

Sequence length	437 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the transfer of a farnesyl moiety from farnesyl pyrophosphate to a cysteine at the fourth position from the C-terminus of several proteins. The beta subunit is responsible for peptide-binding.
Catalytic activity	Farnesyl diphosphate + protein-cysteine = S-farnesyl protein + diphosphate.
Cofactor	Binds 1 zinc ion per subunit.
Subunit structure	Heterodimer of an alpha and a beta subunit. Ref.6
Sequence similarities	Belongs to the protein prenyltransferase subunit beta family. Contains 5 PFTB repeats.
