FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an integral plasma membrane glycoprotein of the liver, islet beta cells, intestine, and kidney epithelium. The encoded protein mediates facilitated bidirectional glucose transport. Because of its low affinity for glucose, it has been suggested as a glucose sensor. Mutations in this gene are associated with susceptibility to diseases, including Fanconi-Bickel syndrome and noninsulin-dependent diabetes mellitus (NIDDM). Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]
PHENOTYPE: Homozygous null mice are hyperglycemic with hypoinsulinemia and die within 2-3 weeks of life displaying increased plasma levels of glucagon, free fatty acids and beta-hydroxybutyrate, abnormal glucose tolerance, and altered postnatal development of pancreatic islets.
