• PubMed Abstract: 
  

Autophagy-related protein Atg8 is ubiquitous in all eukaryotes. It is involved in the Atg8-PE ubiquitin-like conjugation system, which is essential for autophagosome formation. The structures of Atg8 from different species are very similar and share a ubiquitin-fold domain at the C-terminus. In the 2.40 A crystal structure of Atg8 from the silkworm Bombyx mori reported here, the ubiquitin fold at the C-terminus is preceded by two additional helices at the N-terminus.
