(G) Control or UBQLN‐KD cells were starved for increasing periods. Where indicated, BAF A was added to the starvation medium (+B). Cell lysates were analysed by Western blot for their content in LC3‐II. Loading control: transferrin receptor (TfR). BAF A, bafilomycin A1; GFP, green fluorescent protein; KD, knockdown; siRNA, short interfering RNA; UBQLN, ubiquilin.
