The glucose transporter families SGLT and GLUT: molecular basis of normal and aberrant function

Glucose enters eucaryotic cells via 2 different types of membrane associated carrier proteins, the Na+-coupled glucose transporters (SGLT) and glucose transporter facilitators (GLUT). Three members of the SGLT family function as sugar transporters (SGLT1 and SGLT2) or sensors (SGLT3). The human GLUT family consists of 14 members, of which 11 have been shown to catalyze sugar transport. The individ…
