General description
There are four hexokinases in most vertebrates, hexokinase I, II, III, and IV; HK2 is hexokinase-II (Hexokinase-2). Hexokinase-2 (HK2) or alternatively Hexokinase type II (HK II) or muscle form hexokinase is the predominant hexokinase enzyme expressed in insulin-responsive tissues like skeletal muscle and other tissues like brain. HK2 is also expressed at high levels in many cancers which is thought to aid in their survival. HK2 is responsible for the phosphorylation of hexoses such as glucose into glucose-6-phosphate; the initial step in carbohydrate metabolism. HK2 is typically associated with mitochondrial membranes. Over expression of HK2 is associated with resistance to cell death and often given the name of the “Warburg Effect” after the initial discover of the relationship between energy metabolism and cell death. While HK2 overexpression has been shown to be one of the mechanisms for the survival of cancers, it has also been shown to facilitate the survival of normal, non-cancerous tissues such as neurons and astrocytes in response to injury and stress. Thus because of its relationship to energy metabolism and its connection with cell death and survival, HK2 is being examined as a potential target for treatment of everything from brain tumors to aging. EMD-Millipore’s Anti-HK2 mouse monoclonal has been tested in western blot on Jurkat, HeLa, and HEK293 cell lysates and in paraffin embedded immunohistochemistry on esophagus and human lung cancer tissues and in flow cytometry on K562 cells in culture.
~102 kDa observed. Uncharacterized bands may appear in some lysate(s).
