Atg11, as scaffold proteins, mainly mediated the formation of autophagosome in selective autophagy through its many helical domains. Selective autophagy could specifically remove damaged biomolecules and organelles and played an important role in the intracellular material turnover of eukaryotes. Firstly, the structural features of Atg11 were briefly introduced. Secondly, the roles of Atg11 in three kinds of selective autophagy including Cvt pathway, peroxidase autophagy and mitochondrial autophagy were introduced. Finally, the other features of Atg11 were briefly summarized. This review systematically summarized the research progress of Atg11 in recent years, so as to provide references for the formation of autophagosomes and the function of Atg11 in this process.
