Abstract
Methods for delivering non-mitochondrial proteins to mitochondria are provided. Also provided are nucleic acid constructs comprising a coding sequence encoding a DNA-binding polypeptide, fused to a mitochondrial targeting sequence (MTS) and a nuclear export signal (NES), and the encoded proteins. The construct successfully delivers DNA binding proteins to the mitochondrion. A chimeric methylase based on the above construct is successfully delivered to mitochondria, resulting in modification of mtDNA.
