Autophagy shows its animal side.

ABSTRACT

Most autophagy genes have been discovered in the single-celled yeast Saccharomyces cerevisiae, and little is known about autophagy genes that are specific to multicellular animals. In this issue, Tian et al. (2010) now identify four new autophagy genes one specific to the nematode Caenorhabditis elegans and three conserved from worms to mammals.
