Summary: Enables glucokinase activity. Involved in calcium ion import; intracellular glucose homeostasis; and positive regulation of insulin secretion. Acts upstream of or within several processes, including NADP metabolic process; carbohydrate phosphorylation; and regulation of insulin secretion. Located in cytosol; mitochondrion; and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; musculoskeletal system; and sensory organ. Used to study familial hyperinsulinemic hypoglycemia 3; hyperinsulinemic hypoglycemia; maturity-onset diabetes of the young type 2; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in artery disease (multiple) and glucose metabolism disease (multiple). Orthologous to human GCK (glucokinase).

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.
