NCBI Summary for SLC2A4
This gene is a member of the solute carrier family 2 (facilitated glucose transporter) family and encodes a protein that functions as an insulin-regulated facilitative glucose transporter. In the absence of insulin, this integral membrane protein is sequestered within the cells of muscle and adipose tissue. Within minutes of insulin stimulation, the protein moves to the cell surface and begins to transport glucose across the cell membrane. Mutations in this gene have been associated with noninsulin-dependent diabetes mellitus (NIDDM). [provided by RefSeq, Jul 2008]
UniProt Comments for SLC2A4
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.
