Evidence:Substrate In Vitro Evidence: 2-deoxyglucose, glucose, fructose, monosaccharide (Xenopus oocytes) Permutt, M. A.; Koranyi, L.; Keller, K.; Lacy, P. E.; Scharp, D. W.; Mueckler, M. Cloning and functional expression of a human pancreatic islet glucose-transporter cDNA. Proc. Nat. Acad. Sci. 86: 8688-8692, 1989. Kinetic analysis of the liver-type (GLUT2) and brain-type (GLUT3) glucose transporters in Xenopus oocytes: substrate specificities and effects of transport inhibitors. Biochem J. 1993 Mar 15; 290 ( Pt 3): 701-6. Substrate In Vivo Evidence: Homozygous mice deficient in GLUT2 are hyperglycemic and relatively hypoinsulinemic and have elevated plasma levels of glucagon, free fatty acids, and beta-hydroxybutyrate. In vivo, their glucose tolerance was abnormal. In vitro, beta-cells displayed loss of control of insulin gene expression by glucose and impaired glucose-stimulated insulin secretion.

Tissue Distribution Evidence: The highest amounts of GLUT2 mRNA are present in liver with lower amounts in kidney and small intestine.
