GLUT4 an integral membrane facilitative glucose transporter. One of 13 members of the human equilibrative glucose transport protein family. Its surface expression is regulated by insulin. Has two internalization sequences, a dileucine repeat present in the C-terminus and a FxxY motif in the amino-terminal end. Associates with an intracellular tubulo-vesicular compartment under low plasma conditions. The binding of insulin to the insulin receptor (a typosine kinase) leads to the rapid translocation of GLUT4 to the cell surface, increasing cellular glucose transport activity. Its translocation to the plasma membrane is also stimulated by exercise, but independent from insulin signaling. This insulin-independent pathway may be regulated by AMPK. Note: This description may include information from UniProtKB.
