In mammals, glucose transport is mediated by five structurally related glucose transporters that show a characteristic cell-specific expression. However, the rat brain/HepG2/erythrocyte-type glucose transporter GLUT-1 is expressed at low levels in most cells. The reason for this coexpression is not clear. GLUT-1 is negatively regulated by glucose. Another family of proteins, glucose-regulated proteins (GRPs), is also ubiquitously expressed and stimulated by glucose deprivation and other… CONTINUE READING
