Fig. 4. ARD1 mediates Hsp70 acetylation to increase autophagy.

Fig. 4

a Cells were serum-starved overnight and treated with TNFα for 30 min. Protein acetylation was determined by immunoprecipitation with anti-Hsp70 antibody followed by western blotting for an antibody recognizing internal acetyl-lysine residues or anti-Hsp70 antibody. β-Actin was used as a protein loading control. b Cells were treated as described in (a) and lysates were detected by immunoprecipitation as described in the figure. c Cells were transiently cotransfected with HA-ARD1 or Flag Ctrl, Flag vector, Flag-Hsp70 WT, Flag-Hsp70 mutants, serum-starved overnight, and then treated with TNFα for 1 h. Cell lysates were lysed for the detection of the expression of the protein shown in the figure. The association between Vsp34 and Beclin-1 was analyzed by immunoprecipitation with anti-Beclin-1 antibody followed by western blotting for anti-Vsp34 or anti-Hsp70 antibodies
