This gene encodes a major glucose transporter in the mammalian blood-brain barrier. The encoded protein is found primarily in the cell membrane and on the cell surface, where it can also function as a receptor for human T-cell leukemia virus (HTLV) I and II. Mutations in this gene have been found in a family with paroxysmal exertion-induced dyskinesia. [provided by RefSeq, Apr 2013]

UniProtKB/Swiss-Prot for SLC2A1 Gene
Facilitative glucose transporter. This isoform may be 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.
Glucose is an essential source of energy for mammalian cells, and is also used as a substrate in protein and lipid synthesis. Given its hydrophilic nature, glucose must be transported into the cell by dedicated transporters; these are encoded by genes known collectively as the facilitative glucose transporter gene family (GLUT). There are 13 known members of the GLUT family. Glucose transporters maintain a ready supply of glucose for the cell's metabolic activity. During growth and division, the energy demands of a cell are increased; it needs glucose to generate ATP and biomass. Cancer cells, which proliferate at a greater rate, thus require more energy than a normal cell. Aerobic glycolysis - often observed in tumor cells, and also known as the Warburg effect - relies on a high rate of glucose uptake, since the generation of ATP by this process is far less efficient than oxidative phosphorylation. Glucose transporters, in particular GLUT1, have therefore become a target of interest in cancer research, as have glycolytic inhibitors.
