During production, two errors were introduced to the article listed above. The first is in the title, which should read “Deletion of Both Rab-GTPase–Activating Proteins TBC1D1 and TBC1D4 in Mice Eliminates Insulin- and AICAR-Stimulated Glucose Transport.” The second is in the first sentence of the abstract, which should read “The Rab-GTPase–activating proteins TBC1D1 and TBC1D4 (AS160) were previously shown to regulate GLUT4 translocation in response to activation of AKT and AMP-dependent kinase.” The editors regret the errors.

The online version reflects these changes.
