Abstract Peroxisomes are dynamic organelles essential for lipid metabolism, oxidative balance, and cellular stress responses. Their dysfunction contributes to various diseases, including metabolic and neurodegenerative disorders. Selective autophagy, or pexophagy, preserves peroxisomal quality by removing damaged or excess peroxisomes. Here, we propose a novel ATM-PINK1-STUB1-ABCD3-SQSTM1 signaling cascade that orchestrates pexophagy in response to peroxisomal impairment.
