  • Publication number: 20240093229
    Abstract: An expression vector containing appropriate mitochondrion-targeting sequences (MTS) and appropriate 3?UTR sequences provides efficient and stable delivery of a mRNA encoding a protein (CDS) to the mitochondrion of a mammalian cell. The MTS and 3?UTR sequences guide the CDS mRNA from the nuclear compartment of the cell to mitochondrion-bound polysomes, where the CDS is translated. This provides an efficient translocation of a mature functional protein into the mitochondria. A method of targeting mRNA expressed in the nuclear compartment of a mammalian cell to the mitochondrion is also provided. The vector and methods can be used to treat defects in mitochondrial function.
