Structural biology of the macroautophagy machinery

  • Leon H. Chew
  • Calvin K. Yip


Macroautophagy is a conserved degradative process mediated through formation of a unique doublemembrane structure, the autophagosome. The discovery of autophagy-related (Atg) genes required for autophagosome formation has led to the characterization of approximately 20 genes mediating this process. Recent structural studies of the Atg proteins have provided the molecular basis for their function. Here we summarize the recent progress in elucidating the structural basis for autophagosome formation.
