Engineered meganucleases for modifying human mitochondrial dna
A recently granted patent (Publication Number: US11866747B2) discloses a novel mitochondria-targeting engineered meganuclease (MTEM) designed to bind and cleave specific recognition sequences within mitochondrial genomes of eukaryotic cells. The MTEM consists of an engineered meganuclease fused with a mitochondrial transit peptide (MTP), with the engineered meganuclease sequence specified in SEQ ID NO: 9. Additionally, the MTP sequence is detailed in SEQ ID NO: 45 and is attached at the N-terminus of the engineered meganuclease. Furthermore, the MTEM may also be linked to a nuclear export sequence (NES) detailed in SEQ ID NO: 46 at the C-terminus.
Moreover, the patent encompasses the use of polynucleotides encoding the MTEM, with similar structural and functional characteristics as the MTEM described above. These polynucleotides can be incorporated into recombinant adeno-associated viruses (AAVs) for targeted delivery and expression of the MTEM within eukaryotic cells. The AAVs containing the polynucleotide encoding the MTEM are equipped with a promoter, such as the CAG promoter, operably linked to the nucleic acid sequence encoding the MTEM. Additionally, specific AAV capsids, like AAV9, can be utilized for packaging the polynucleotide-containing AAVs, further enhancing their targeted delivery capabilities. The patent outlines various combinations and configurations of the MTEM, MTP, NES, and AAV components, providing a comprehensive framework for utilizing this innovative technology in genetic engineering applications.
