GlycoErase™ GCK Knockout CHO-K1 Cell Line (CAT#: GLJF-0825-JF284)

Description	GlycoErase™ GCK knockout CHO-K1 cell line is a CHO-K1 model in which GCK expression has been eliminated. GCK encodes glucokinase, a hexokinase variant critical for glucose-stimulated insulin secretion in the pancreas and glucose utilization in the liver. Mutations are linked to diabetes and hypoglycemia. This knockout model offers a system for studying glucose sensing, pancreatic beta-cell function, and liver glucose regulation, while enabling drug discovery for diabetes and metabolic syndromes.

Summary	This gene encodes a member of the hexokinase family of proteins. Hexokinases phosphorylate glucose to produce glucose-6-phosphate, the first step in most glucose metabolism pathways. 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. The use of multiple promoters and alternative splicing of this gene result in distinct protein isoforms that exhibit tissue-specific expression in the pancreas and liver. In the pancreas, this enzyme plays a role in glucose-stimulated insulin secretion, while in the liver, this enzyme is important in glucose uptake and conversion to glycogen. Mutations in this gene that alter enzyme activity have been associated with multiple types of diabetes and hyperinsulinemic hypoglycemia.
