In distinction, we observed that C99-3Y/A strongly accumulates at the cell floor when the two the proteasome is inhibited by MG132 and the lysosomal function is disrupted with CQ (Fig. 7C, lane four)
Apparently, MG132 elevated the stages of AICDc even in the absence of ubiquitination (Fig. 5B, lanes two and 4), supporting the notion that processing by c-secretase is favored for the…
