Rab proteins geranylgeranyltransferase component A 2 is an enzyme that in humans is encoded by the CHML gene.

The product of the CHML gene supports geranylgeranylation of most Rab proteins and may substitute for REP-1 in tissues other than retina. CHML is localized close to the gene for Usher syndrome type II.
