Protein
Geranylgeranyl transferase type-1 subunit beta
Function
Catalyzes the transfer of a geranyl-geranyl moiety from geranyl-geranyl pyrophosphate to a cysteine at the fourth position from the C-terminus of proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X. Known substrates include RAC1, RAC2, RAP1A and RAP1B (By similarity).
Similarity
Belongs to the protein prenyltransferase subunit beta family.
