Anti-HKIII antibodies enable researchers to detect and measure the HKIII antigen in biological samples. This target is a reported synonym of the HK3 gene, which encodes hexokinase 3. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of HKIII has a canonical amino acid length of 923 residues and a protein mass of 99 kilodaltons. It is reported to be notably expressed in the spleen, lymph node, lung, and bone marrow. Other names for this target antigen include HXK3 and ATP:D-hexose 6-phosphotransferase.
