In yeast, the novel protein Atg40 is enriched in the cortical and cytoplasmic endoplasmic reticulum (ER), and loads these ER subdomains into autophagosomes to facilitate ER autophagy; Atg39 localizes to the perinuclear ER and induces autophagic sequestration of part of the nucleus, thus ensuring cell survival under nitrogen-deprived conditions.
