Gene

CHM

ENSG00000188419
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 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. Alternatively spliced transcript variants have been found for this gene.

Gene Knockout Kits Provide Superior Editing Efficiency in iPSC, Immortalized, and Primary Cells and Consistent Protein Depletion Using the XDel Design

Figure 1. A) On-target editing efficiency of XDel multiple guide design (MGKO) (pink bars) vs their 3 respective single-guide RNAs (blue bars) across 7 endogenous target loci transfected in two immortalized (IMM) and two iPSC cell lines. Each transfection was performed in triplicate and data were analyzed via NGS by EditCo’s proprietary software analysis. B) Western blot analyses for all 5 knockout target genes indicate a complete depletion of proteins across the 3 specified time points (days 7, 14, and 21) relative to the negative controls. Knockout cell pools for the target genes were generated by nucleofecting U2OS cells with multi-guide sgRNA and Cas9 (as RNPs). A negative control pool was also transfected for each target using non-targeting sgRNA.
