Summaries for GCK Gene

Entrez Gene Summary for GCK Gene

  • Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. Alternative splicing of this gene results in three tissue-specific forms of glucokinase, one found in pancreatic islet beta cells and two found in liver. The protein localizes to the outer membrane of mitochondria. In contrast to other forms of hexokinase, this enzyme is not inhibited by its product glucose-6-phosphate but remains active while glucose is abundant. Mutations in this gene have been associated with non-insulin dependent diabetes mellitus (NIDDM), maturity onset diabetes of the young, type 2 (MODY2) and persistent hyperinsulinemic hypoglycemia of infancy (PHHI).

GeneCards Summary for GCK Gene

GCK (Glucokinase) is a Protein Coding gene. Diseases associated with GCK include Hyperinsulinemic Hypoglycemia, Familial, 3 and Mody, Type Ii. Among its related pathways are Glucagon signaling pathway and Insulin secretion. GO annotations related to this gene include magnesium ion binding and phosphotransferase activity, alcohol group as acceptor. An important paralog of this gene is HK2.

UniProtKB/Swiss-Prot for GCK Gene

  • Catalyzes the initial step in utilization of glucose by the beta-cell and liver at physiological glucose concentration. Glucokinase has a high Km for glucose, and so it is effective only when glucose is abundant. The role of GCK is to provide G6P for the synthesis of glycogen. Pancreatic glucokinase plays an important role in modulating insulin secretion. Hepatic glucokinase helps to facilitate the uptake and conversion of glucose by acting as an insulin-sensitive determinant of hepatic glucose usage.

Function for GCK Gene

Molecular function for GCK Gene

GENATLAS Biochemistry:
glucokinase,expressed in liver and islet beta cells of pancreas,glucose specific,primary regulator of glucose-controlled insulin secretion,catalyzing the first step of glycolysis,energy pathway
UniProtKB/Swiss-Prot CatalyticActivity:
ATP + D-glucose = ADP + D-glucose 6-phosphate.
UniProtKB/Swiss-Prot EnzymeRegulation:
The use of alternative promoters apparently enables the type IV hexokinase gene to be regulated by insulin in the liver and glucose in the beta cell. This may constitute an important feedback loop for maintaining glucose homeostasis. Subject to allosteric regulation. Low glucose and high fructose-6-phosphate triggers association with the inhibitor GKRP followed by sequestration in the nucleus.
UniProtKB/Swiss-Prot Function:
Catalyzes the initial step in utilization of glucose by the beta-cell and liver at physiological glucose concentration. Glucokinase has a high Km for glucose, and so it is effective only when glucose is abundant. The role of GCK is to provide G6P for the synthesis of glycogen. Pancreatic glucokinase plays an important role in modulating insulin secretion. Hepatic glucokinase helps to facilitate the uptake and conversion of glucose by acting as an insulin-sensitive determinant of hepatic glucose usage.
