Glut4 is a member of the Solute Carrier Family 2 (SLCA2). The protein is encoded by the SLC2A4 gene and is involved in the insulin-dependent trafficking of glucose to the plasma membrane. The protein is crucial to glucose transport and genetic mutations can be involved in Non-Insulin Dependent Diabetes Mellitus (Diabetes). Glut4 is typically found in skeletal and cardiac muscle, as well as adipose tissue.
