Gene Gene information from NCBI Gene database.
Entrez ID 1121
Gene name CHM Rab escort protein
Gene symbol CHM
Synonyms (NCBI Gene)
DXS540GGTAHSD-32REP-1TCD
Chromosome X
Chromosome location Xq21.2
Summary 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
