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 additional components such as a nuclear export sequence (NES) for enhanced functionality. The amino acid sequences of the components are specified in the claims, providing a detailed blueprint for the construction of the MTEM.
Furthermore, the patent also covers the use of polynucleotides encoding the MTEM and their incorporation into recombinant adeno-associated viruses (AAVs) for targeted delivery into cells. The AAVs are designed to carry the MTEM gene along with specific promoters and capsids for efficient gene expression and delivery. The claims outline various configurations of the MTEM, MTP, NES, and promoters, emphasizing the versatility and customization options available for researchers looking to utilize this technology for mitochondrial genome editing. Overall, the patent provides a comprehensive framework for the development and application of the MTEM technology in genetic engineering and therapeutic interventions.
