We found a system of Na+-dependent uptake of fructose by rat renal brush-border membrane vesicles. It consisted of two saturable components, and was thought to involve at least two transporters. rNaGLT1, a novel glucose transporter in rat kidney, showed fructose uptake as well as α-methyl-D-glucopyranoside uptake by transfected HEK293 cells. The features of the lower affinity type of fructose transporter in the brush-border membranes, such as affinity and substrate recognition, were very comparable with those of rNaGLT1-transfected HEK293 cells. These results indicated that rNaGLT1 is a primary fructose transporter in rat renal brush-border membranes.
