Summary: Enables glucosamine kinase activity and hexokinase activity. Involved in canonical glycolysis and glucose 6-phosphate metabolic process. Predicted to be located in mitochondrial outer membrane. Predicted to be active in cytosol and mitochondrion. Is expressed in several structures, including adult head; cuboidal/columnar epithelium; dorsal ectoderm; dorsal epidermis primordium; and embryonic epipharynx. Used to study glucose metabolism disease. Human ortholog(s) of this gene implicated in several diseases, including Charcot-Marie-Tooth disease type 4G; anemia (multiple); artery disease (multiple); glucose metabolism disease (multiple); and hematologic cancer (multiple). Orthologous to several human genes including GCK (glucokinase). [provided by Alliance of Genome Resources, Dec 2024]
