A fluorescent tool set for yeast Atg proteins

Abstract

Fluorescence microscopy of live cells is instrumental in deciphering the molecular details of autophagy. To facilitate the routine examination of yeast Atg proteins under diverse conditions, here we provide a comprehensive tool set, including (1) plasmids for the expression of GFP chimeras at endogenous levels for most Atg proteins, (2) RFP-Atg8 constructs with improved properties as a PAS marker, and (3) plasmids for the complementation of common yeast auxotrophic markers. We hope that the availability of this tool set will further accelerate yeast autophagy research.
