Several figures were not prepared in accordance with JBC policies. Specifically, groupings of immunoblot images from different parts of the same gel were not made explicit in the following figures: Fig. 1A (GLUT4), Fig. 2D (sortilin and TfR), Fig. 3A (GLUT4, VAMP-2, and sortilin), Fig. 5B (all images), Fig. 5C (LDM), Fig. 5D (GLUT4), Fig. 6C (GLUT4 and right tubulin), Fig. 6E (sortilin and Vps35), and Fig. 6F (GLUT4).
White lines have been added to indicate where the blot images were joined. This correction does not affect the interpretation or conclusions of this work.
