Active PKB, phosphorylates

and inhibits the GTP→GDP hydrolysis activity of two GAP

proteins - AS160 and RGC

#Id: 9694

#XL - T Zoology

Phosphorylation causes the binding of AS160 to the 

14-3-3 protein that sequesters it in the cytosol away from its target Rab proteins

In the basal state, 

GAPs inhibit RalA and Rab10 function by enhancing their rates of GTP hydrolysis

#Id: 9696

#XL - T Zoology

Phosphorylation of both GAPs by PKB allows RalA and the Rab10 to accumulate in their active GTP-bound states, enabling them to facilitate GSVs targeting and fusion

In resting cells, 

GSK3 is catalytically active which phosphorylates and inhibits glycogen synthase, thus blocking glycogen synthesis from glucose
