GLUT 2 is a transmembrane protein which is involved in passive transport of glucose over cellular membranes of Liver, beta cells, hypothalamus, basolateral membrane small intestine. It has high capacity but low affinity (high Km, ca. 5 mM) part of "the glucose sensor" in ß-cells. Carrier for glucose. Fructose uses the GLUT5 transporter.
