Subject: How is insulin de-activated once it helps transport glucose?

I understand insulin binds to a receptor on the cell wall that signals 
inside the cell to summon one of the GLUT proteins that the glucose is 
transported through, but what "turns off" the insulin after it has signaled 
the GLUT protein?  (Can someone send me a detailed diagram of the binding 
and signaling process?)
