Definition: A glucose transport protein found in mature MUSCLE CELLS and ADIPOCYTES. It promotes transport of glucose from the BLOOD into target TISSUES. The inactive form of the protein is localized in CYTOPLASMIC VESICLES. In response to INSULIN, it is translocated to the PLASMA MEMBRANE where it facilitates glucose uptake.
Other names Insulin Responsive Glucose Transporter; Glucose Transporter, Insulin-Responsive; GLUT 4 Protein; Solute Carrier Family 2, Facilitated Glucose Trans; SLC2A4 Protein; Insulin-Responsive Glucose Transporter; GLUT4 Protein; GLUT-4 Protein
