Also known as: GKRP
Summary: Predicted to enable several functions, including carbohydrate binding activity; enzyme inhibitor activity; and fructose-6-phosphate binding activity. Involved in positive regulation of glucokinase activity. Acts upstream of or within cellular glucose homeostasis; negative regulation of glucokinase activity; and protein import into nucleus. Located in nucleus. Is expressed in diencephalon lateral wall mantle layer; liver left lobe; liver right lobe; midbrain mantle layer; and retina. Human ortholog(s) of this gene implicated in end stage renal disease and type 2 diabetes mellitus. Orthologous to human GCKR (glucokinase regulator).

The GCKR-P446L gene variant predisposes to raised blood cholesterol and lower blood glucose in the P446L mouse-a model for GCKR rs1260326.
Title: The GCKR-P446L gene variant predisposes to raised blood cholesterol and lower blood glucose in the P446L mouse-a model for GCKR rs1260326.
This study showed that Sirt2-dependent GKRP deacetylation improves impaired HGU and suggest that it may be a therapeutic target for type 2 diabetes.
Title: Sirt2 facilitates hepatic glucose uptake by deacetylating glucokinase regulatory protein.
Given that acetylated GKRP may affiliate with type-2 diabetes mellitus (T2DM), understanding the mechanism of GKRP acetylation in the liver could reveal novel targets within the GK-GKRP pathway, for treating T2DM and other metabolic pathologies.
Title: Acetylation of glucokinase regulatory protein decreases glucose metabolism by suppressing glucokinase activity.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
