Anti-glycerol-3-phosphate dehydrogenase 2 (mitochondrial) antibodies enable researchers to detect and measure the glycerol-3-phosphate dehydrogenase 2 (mitochondrial) antigen in biological samples. This target is a reported synonym of the GPD2 gene, which encodes glycerol-3-phosphate dehydrogenase 2. This protein is known to function in metabolic processes, among other biological roles. The human version of glycerol-3-phosphate dehydrogenase 2 (mitochondrial) has a canonical amino acid length of 727 residues and a protein mass of 80.9 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. Other names for this target antigen include GDH2, GPDM, and mGDH.
