Most mammalian cells transport glucose through a family of membrane proteins known as glucose transporters.
Molecular cloning of these glucose transporters has identified a family of closely related genes that encodes at least 7 proteins ( Glut-1 to Glut-7 , MW 40-60kD) and Sodium Glucose Co-Transporter-1 (SGLT-1, 662aa; ~75kD).
Individual member of this family have identical predicted secondary structures with 12 transmembrane domains.
Both N- and C-termini are predicted to be cytoplasmic.
Most differences in sequence homology exist within the four hydrophilic domains that may play a role in tissue-specific targeting.
Glut isoforms differ in their tissue expression, substrate specificity and kinetic characteristics.
Glut-1 mediates glucose transport into red cells, throughout the blood brain barrier and supply glucose to most cells.
Glut-2 provides glucose to the liver and pancreatic cells.
Glut-3 is the main transporter in neurons.
Glut-4 is primarily expressed in muscle and adipose tissue and regulated by insulin.
Glut-5 transports fructose in intestine and testis.
Glut-6 is a pseudogene and unlikely to be expressed at the protein level.
Glut-7 is expressed in liver and other gluconeogenic tissues and mediates glucose flux across endoplasmic reticulum membrane.
Glut-8 is found in adult testis and placenta.
Human Glut-9 is expressed in spleen, peripheral leukocytes and brain.
Human Glut-10 (541aa, chromosome 20q13.1; ~30-35% homology with Glut-3 and Glut-8) has been identified as a candidate gene for NIDDM susceptibility.
It is widely expressed with highest levels in liver and pancreas.
Glut-11 (496aa, chromosome 22q11.2; ~41% identity with Glut-5) is expressed in heart and skeletal muscle.
Glut-12 (human 617aa, , monkey 621aa; ~ 50kD; ~30% homology with Glut-4 and 40% with Glut-10) is expressed in skeletal muscle, adipose tissue, and small intestine.
