External Ids for GCKR Gene
This gene encodes a protein belonging to the GCKR subfamily of the SIS (Sugar ISomerase) family of proteins. The gene product is a regulatory protein that inhibits glucokinase in liver and pancreatic islet cells by binding non-covalently to form an inactive complex with the enzyme. This gene is considered a susceptibility gene candidate for a form of maturity-onset diabetes of the young (MODY). [provided by RefSeq, Jul 2008]
GeneCards Summary for GCKR Gene
GCKR (Glucokinase (Hexokinase 4) Regulator) is a Protein Coding gene. Diseases associated with GCKR include maturity-onset diabetes of the young and cardiovascular disease risk factor. Among its related pathways are Metabolism and MPS VI - Maroteaux-Lamy syndrome. GO annotations related to this gene include enzyme binding and carbohydrate binding.
UniProtKB/Swiss-Prot for GCKR Gene
Inhibits glucokinase (GCK) by forming an inactive complex with this enzyme. The affinity of GCKR for GCK is modulated by fructose metabolites: GCKR with bound fructose 6-phosphate has increased affinity for GCK, while GCKR with bound fructose 1-phosphate has strongly decreased affinity for GCK and does not inhibit GCK activity.
