    ..A CEN plasmid-encoded YMIP protein restored normal MIP activity along with respiratory competence. Thus, YMIP is a functional homolog of RMIP and represents a new component of the yeast mitochondrial import machinery. ..

    ..Our results suggest that Icp55 is critical for stabilization of the mitochondrial proteome and illustrate how the N-proteome can serve as rich source for a systematic analysis of mitochondrial protein targeting, cleavage and turnover. ..
