SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,organelle,endoplasmic reticulum

basic FUNCTION	may be a single membrane channel protein acting both as a hydrolase and a translocase
	key enzyme in homeostatic regulation of blood glucose levels
	may underlie variation in fasting glucose, though it is possible that ABCB11, which is expressed primarily in liver, may also contribute to such variation
	Glucokinase (GCK) and G6PC2 regulate the glucose-cycling step in pancreatic beta-cells and may regulate insulin secretion

REGULATION

induced by

endoplasmic reticulum stress (increases glucose-6-phosphatase and glucose cycling in liver cells)

ASSOCIATED DISORDERS

corresponding disease(s)

Susceptibility

to type 2 diabetes to variation of fasting glucose concentrations

Variant & Polymorphism SNP	SNPs from G6PC2 associated with type 2 diabetes (G6PC2 genetic variants were associated to both first- and second-phases insulin secretion)
	significant association between the SNP rs563694 and fasting glucose concentrations

Candidate gene	G6PC2 inhibitors may be an attractive new approach for the treatment of insulin secretion defects in type 2 diabetes
