human ... GCK(2645)
Descrição geral
The gene encoding glucokinase (GCK) is alternatively spliced to generate three different forms of the enzyme; one found in the pancreas and two found in the liver. The enzyme is expressed as a monomer and possesses one glucose-binding site.[1] The gene encoding GCK is localized on human chromosome 7.[2] Recombinant human liver glucokinase (Accession# NP_277042)) has a C-terminal FLAG tag and has 474 amino acid residues.
Ações bioquímicas/fisiológicas
Glucose is phosphorylated to glucose-6-phosphate by glucokinases. The main function of glucokinase (GCK) is to regulate carbohydrate metabolism. The enzyme triggers the release of insulin in β-cells of pancreas.[1] It can be useful for studies including enzyme kinetics, activator screening and kinase selectivity. Mutation in the gene encoding this protein is associated with a rare form of diabetes and the protein may also have a role in type 2 diabetes.[2]

Glucokinase (GK), the hexokinase involved in glucose sensing in pancreatic β cells, is also expressed in hypothalamic tanycytes, which cover the ventricular walls of the basal hypothalamus and are implicated in an indirect control of neuronal activity by glucose. Previously
