Flanagan MD, et al. (2013) An Atg10-like E2 enzyme is essential for cell cycle progression but not autophagy in Schizosaccharomyces pombe. Cell Cycle 12(2):271-7
Abstract: Many proteins involved in autophagy have been identified in the yeast Saccharomyces cerevisiae. For example, Atg3 and Atg10 are two E2 enzymes that facilitate the conjugation of the ubiquitin-like proteins (Ubls) Atg8 and Atg12, respectively. Here, we describe the identification and characterization of the predicted Atg10 homolog (SpAtg10) of the evolutionarily distant Schizosaccharomyces pombe. Unexpectedly, SpAtg10 is not essential for autophagy. Instead, we find that SpAtg10 is essential for normal cell cycle progression, and for responses to various stress conditions that perturb the cell cycle, independently of Atg12 conjugation. Taken together, our data indicate that autophagic Ubl conjugation pathways differ between eukaryotes and, furthermore, that enzymes such as Atg10 may have additional functions in controlling key cellular processes such as cell cycle progression. Atg10-related proteins are found from yeast to humans, and, thus, this study has implications for understanding the functions of this protein family in Ubl conjugation in eukaryotes.
