TBC1D1

And that all activates AMP kinase, which is the cell's energy sensor.

AMP kinase, like kinases do, phosphorylates TBC1D1, the sister protein to TBC1D4, and it releases a different break on the same vesicles storing GLUT4, which again end up on the surface of the cell and sugar can come in.

But this one needs no insulin at all.

The persistence of the effect is related to TBC1D4, which carries phosphorylation sites for both AKT and AMP kinase, and it responds on a delay.
