Anti-MNADK antibodies enable researchers to detect and measure the MNADK antigen in biological samples. This target is a reported synonym of the NADK2 gene, which encodes NAD kinase 2, mitochondrial. This protein is known to function in protein phosphorylation, among other biological roles. The human version of MNADK has a canonical amino acid length of 442 residues and a protein mass of 49.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the mitochondria of cells and widely expressed in many tissue types. MNADK is a member of the NAD kinase protein family.
