CEF, a Sec24 homologue of Arabidopsis thaliana, enhances the survival of yeast under oxidative stress conditions

Abstract

Budding yeast strains that produced the Arabidopsis thaliana protein CEF or its amino-terminal proline-rich domain were more tolerant to hydroperoxides. CEF is homologous to animal and yeast Sec24 proteins. These data suggest that CEF plays a protective role through protein transport during growth under pro-oxidant conditions.
