Anti-CDGS antibodies enable researchers to detect and measure the CDGS antigen in biological samples. This target is a reported synonym of the PMM2 gene, which encodes phosphomannomutase 2. This protein is known to function in protein glycosylation, among other biological roles. The human version of CDGS has a canonical amino acid length of 246 residues and a protein mass of 28.1 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CDG1 and CDG1a.
