KEAP1 and lung carcinoma: A549 lung cancer cell line, which harbors mutated Keap1 (G333C), is unable to bind to p62.36 We found that CSE only mildly induced p62 dimer formation in A549 cells, but did not induce any oligomers despite increasing LC3‐II and also LC3‐I at the highest concentrations (Figure S7).
