General annotation (Comments)

Function

Binds unprenylated Rab proteins, presents it to the catalytic Rab GGTase dimer, and remains bound to it after the geranylgeranyl transfer reaction. The component A is thought to be regenerated by transferring its prenylated Rab back to the donor membrane. Also a pre-formed complex consisting of CHM and the Rab GGTase dimer (RGGT or component B) can bind to and prenylate Rab proteins; this alternative pathway is proposed to be the predominant pathway for Rab protein geranylgeranylation.

Subunit structure

Monomer. Can associate with the Rab GGTase dimer (RGGT or component B) prior to Rab protein binding; the association is stabilized by geranylgeranyl pyrophosphate (GGpp). The CHM:RGGT:Rab complex is destabilized by GGpp. Interacts with RAB1B; the interaction is required for RAB1B prenylation. Interacts with RABGGTA. Ref.3 Ref.4

Tissue specificity

Most abundant in the heart, brain, and spleen. Lower levels seen in the lung, liver, muscle and kidney. Extremely low levels seen in the testis.

Sequence similarities

Belongs to the Rab GDI family.
