GLUT1
GLUT's are family of proteins which aim to transport glucose using its downhill gradient across membranes. There are many different GLUT's, however, each has a significantly different role in the transport of molecules. [1] FOr example, GLUT1 is a type of glucose transporter found in the cell membrane of erythrocyte and brain cells and is encoded by the gene SLC2A [2]. The GLUT family of glucose transporters are an example of uniporters, meaning that the carrier protein transports one substrate. Whereas, GLUT 5, for example, is used more often to transport fructose across membranes.
