Anti-CMT1D antibodies enable researchers to detect and measure the CMT1D antigen in biological samples. This target is a reported synonym of the EGR2 gene, which encodes early growth response 2. This protein is known to function in brain development and fat cell differentiation, among other biological roles. The human version of CMT1D has a canonical amino acid length of 476 residues and a protein mass of 50.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus of cells. Other names for this target antigen include AT591 and CMT4E.
