Entrez Gene Summary for CHM Gene

  • This gene encodes component A of the RAB geranylgeranyl transferase holoenzyme. In the dimeric holoenzyme, this subunit binds unprenylated Rab GTPases and then presents them to the catalytic Rab GGTase subunit for the geranylgeranyl transfer reaction. Rab GTPases need to be geranylgeranyled on either one or two cysteine residues in their C-terminus to localize to the correct intracellular membrane. Mutations in this gene are a cause of choroideremia; also known as tapetochoroidal dystrophy (TCD). This X-linked disease is characterized by progressive dystrophy of the choroid, retinal pigment epithelium and retina. Alternative splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Feb 2009]

GeneCards Summary for CHM Gene

CHM (Choroideremia (Rab Escort Protein 1)) is a Protein Coding gene. Diseases associated with CHM include choroideremia and charcot-marie-tooth disease, type 1b. GO annotations related to this gene include GTPase activator activity and Rab geranylgeranyltransferase activity. An important paralog of this gene is CHML.

UniProtKB/Swiss-Prot for CHM Gene

  • Substrate-binding subunit of the Rab geranylgeranyltransferase (GGTase) complex. Binds unprenylated Rab proteins and presents the substrate peptide to the catalytic component B composed of RABGGTA and RABGGTB, 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. Besides, 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.

    Quaternary structure:
    • Monomer. Heterotrimer composed of RABGGTA, RABGGTB and CHM; within this trimer, RABGGTA and RABGGTB form the catalytic component B, while CHM (component A) mediates Rab protein binding. 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 RAB1A, RAB1B, RAB5A, RAB7A and RAB27A and mediates their prenylation.

  • Choroideremia (CHM) [MIM:303100]: An X-linked recessive disease characterized by a slowly progressive degeneration of the choroid, photoreceptors, and retinal pigment epithelium. Affected males develop night blindness in their teenage years followed by loss of peripheral vision and complete blindness at middle age. Carrier females are generally asymptomatic but funduscopic examination often shows patchy areas of chorioretinal atrophy. {ECO:0000269 PubMed:19427510, ECO:0000269 PubMed:21905166, ECO:0000269 PubMed:7951216}. Note=The disease is caused by mutations affecting the gene represented in this entry.
