Red Fluorescent Protein (DsRed) as a Reporter in Saccharomyces cerevisiae

We describe the utilization of a red fluorescent protein (DsRed) as an in vivo marker for Saccharomyces cerevisiae. Clones expressing red and/or green fluorescent proteins with both cytoplasmic and nuclear localization were obtained. A series of vectors are now available which can be used to create amino-terminal (N-terminal) and carboxyl-terminal (C-terminal) fusions with the DsRed protein.
