Hexokinase 3 monoclonal antibody (AT4C12)

Hexokinase is the first enzyme in the glycolytic pathway, catalyzing the transfer of a phosphoryl group from ATP to glucose to form glucose-6-phosphate and ADP. In mammals, four distinct enzymes – types 1 to 4 hexokinases – have been identified. The enzyme is found in most cells, but there is tissue specificity for the particular type of hexokinase. Hexokinase 3 lacks the hydrophobic N-terminal sequence critical for targeting to mitochondria. Hexpkinase 3 may have anabolic functions, providing H6P for glycogen or lipid synthesis.
