  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.
  
  ## Interactions
  
  CHML (gene) has been shown to interact with RAB1A and RAB5A.
