Summary: Enables several functions, including ATP binding activity; D-glucose binding activity; and hexokinase activity. Involved in several processes, including phosphorylation; response to ischemia; and response to ketamine. Located in caveola and mitochondrion. Part of protein-containing complex. Used to study obesity and urinary bladder cancer. Biomarker of colorectal cancer and pulmonary hypertension. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 4G; anemia (multiple); hematologic cancer (multiple); obesity; and retinitis pigmentosa. Orthologous to human HK1 (hexokinase 1). [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.
