GLUT-1 (SP168)

Glucose transporter 1 (or GLUT1), also known as solute carrier family 2, is a protein facilitating the transport of glucose across the plasma membranes of mammalian cells. Several GLUT isoforms have been identified and shown to function in response to insulin and IGF-1 induced signaling. GLUT-1 is detectable in many human tissues including colon, lung, stomach, esophagus, and breast. GLUT-1 is up-regulated in some human cancers from these organs
