MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. This gene encodes hexokinase 2, the predominant form found in skeletal muscle. It localizes to the outer membrane of mitochondria. Expression of this gene is insulin-responsive, and studies in rat suggest that it is involved in the increased rate of glycolysis seen in rapidly growing cancer cells. [provided by RefSeq, Apr 2009]
PHENOTYPE: Embryos homozygous for a knock-out mutation are severely growth retarded and die around E8.5. Interestingly, heterozygous mutant mice are viable and fertile, develop normally and do not exhibit impaired insulin action or glucose tolerance even when challenged with a high-fat diet.
