The GLUT4 (glucose transporter 4) gene, also known as SLC2A4 (solute carrier family 2 member 4) is mapped to human chromosome 17p13.1.The expression of GLUT4 (glucose transporter 4) is the highest in skeletal and adipose tissue.
Application
Anti-GLUT4 (C-terminal) antibody may be used for immunoblotting at a working concentration of 1-2 μg/ml in whole cell lysate of C2C12 and HepG2 cells. A working dilution of 1:3000 was used for immunoblotting in whole cell lysate of HEK-293 cells. . Anti-GLUT4 (C-terminal) antibody has also been used for immunoblotting in CHO-K1 cells. Antibody concentration of 15-20 μg/ml is recommended for immunofluorescence in C2C12 cells.
Anti-GLUT4 (C-terminal) antibody produced in rabbit has been used in western blotting and immunofluorescence assay.
Biochem/physiol Actions
GLUT4 is an insulin-regulated glucose transporter that facilitates the uptake of glusose by fat and muscle cells. Generally restricted to storage vesicles, GLUT4 translocates to the plasma membrane in response to insulin stimulation. The vital function of GLUT4 is regulation of glucose utilization by the cells. Following meal consumption, insulin secreted by the pancreas binds to receptors on the muscle and adipose and activates the PI3K-Akt pathway. Activation of this pathway triggers the secretion of GLUT4 from the vesicles that translocate to the plasma membrane. An overall decrease in the expression of GLUT4 results in diabetes and a selective disruption of GLUT4, in skeletal or adipose tissue, results in insulin resistance

The insulin-sensitive glucose transporter GLUT4 mediates the uptake of glucose into adipocytes and muscle cells. In this study we have used a novel 96-well plate fluorescence assay to study the kinetics of GLUT4 trafficking in 3T3-L1 adipocytes. We have found

One of the most important metabolic actions of insulin is catalysing glucose uptake into skeletal muscle and adipose tissue. This is accomplished via activation of the phosphatidylinositol-3-kinase/Akt signalling pathway and subsequent translocation of GLUT4 from intracellular storage vesicles to the
