Summary: Enables hexokinase activity. Involved in negative regulation of mitochondrial membrane permeability and negative regulation of reactive oxygen species metabolic process. Acts upstream of or within several processes, including carbohydrate phosphorylation; cellular response to leukemia inhibitory factor; and regulation of D-glucose import. Located in mitochondrion. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in obesity and type 2 diabetes mellitus. Orthologous to human HK2 (hexokinase 2). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
