Protein attributes

Sequence length	376 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the transfer of a geranyl-geranyl moiety from geranyl-geranyl pyrophosphate to proteins having the C-terminal sequence Cys-Ile-Ile-Leu or Cys-Val-Leu-Leu. Acts, among other substrates, on Rho1 and Rho2 and CDC42 proteins. Participates in a RAS-like C-terminal modification of proteins involved in nuclear division and bud growth. It is involved in bud positioning and cell polarity. Ref.6
Catalytic activity	Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate.
Cofactor	Binds 1 zinc ion per subunit By similarity.
Subunit structure	Heterodimer of an alpha and a beta subunit.
Miscellaneous	Present with 3940 molecules/cell in log phase SD medium. Ref.7
Sequence similarities	Belongs to the protein prenyltransferase subunit beta family. Contains 4 PFTB repeats.
