Abstract

The insulin-responsive glucose transporter, GLUT-4, is found primarily in adipocytes and skeletal muscle cells, where it is sequestered in a specialized recycling compartment, from which it can be recruited to the cell surface following insulin stimulation. Lower levels of GLUT-4 are also expressed in other tissues, including the kidney, where it is present particularly in cells of the afferent arteriole and juxtaglomerular apparatus (JGA). The exact nature of GLUT-4-containing compartments and their relationship to other regulated trafficking pathways in different cells are not yet well defined. The trafficking of GLUT-4 has been studied in different cells with regulated secretory pathways,..
