Dear Editor,The multiple targeting proteins that have been described in yeast,mammals,and plants have generated intriguing areas of inquiry,including the evolutionary relevance of common proteins shared by different organelles,the mechanisms that determine targeting to each organelle,and,finally,the extent of this phenomenon.Several dual-targeted proteins have been identified in eukaryotic cells.In particular,in plant cells,mitochondria and chloroplasts share over 100 proteins,mitochondria and peroxisomes share approximately a dozen,and plastidial and peroxisomal dual-targeted proteins have been also reported (Zhang and Hu,2010;Carrie and Small,2013).
