Ubiquitin-like autophagy-related gene ATG8 proteins are typically associated with degradative quality control via canonical double-membrane macro-autophagosomes in the cell. ATG8 proteins have now stepped forward in non-canonical pathways in single membrane organelles. The growing interest in non-canonical ATG8 roles has been stimulated by recent links to human conditions, especially in the regulation of inflammation, neurodegeneration and cancers. Here, we summarize the evidence linking non-canonical ATG8s to human pathologies and the quality control of acidic V-ATPase-regulated organelles in the cell.
