Target Background

Facilitative glucose transporter, which is responsible for constitutive or basal glucose uptake. Has a very broad substrate specificity; can transport a wide range of aldoses including both pentoses and hexoses. Most important energy carrier of the brain: present at the blood-brain barrier and assures the energy-independent, facilitative transport of glucose into the brain. In association with BSG and NXNL1, promotes retinal cone survival by increasing glucose uptake into photoreceptors.

  6. Data suggest that GLUT1 functions as tetramer of adjacent dimers of allosteric, alternating access transporters in which (a) cis-allostery is mediated by intra-subunit interaction and (b) trans-allostery requires inter-subunit interaction. Endofacial (vs exofacial) cis-allostery obtains when affinity of un-liganded e1 (endofacial) GLUT1 subunit in one dimer is increased by occupancy of e1 GLUT1 subunit of adjacent dimer. PMID: 29066623
