Family relationships



Geranylgeranyl transferase type-2 subunit alpha (also known as Rab geranyl-geranyltransferase subunit alpha or RabGGTase alpha) is a subunit of the Rab geranylgeranyl transferase [PMID: 18756270]. RabGGTase catalyses the attachment of geranylgeranyl isoprenoids to Rab guanine triphosphatases, which are key regulators in vesicular transport [PMID: 19894725].
