InnateDB Gene IDBG-149698 (Gckr)
Protein Structure
UniProt Annotation
Function 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 (By similarity). {ECO:0000250}.
Subcellular Localization Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}. Note=Under low glucose concentrations, GCK associates with GKRP and the inactive complex is recruited to the hepatocyte nucleus. {ECO:0000250}.
