    Date of Patent: September 19, 2023
    Assignee: EUKARYS
    Inventor: Philippe Jaïs
  • Publication number: 20230265479
    Abstract: The present invention concerns a method for expressing a recombinant DNA molecule in a eukaryotic host cell, comprising the steps of: (a) expressing or introducing at least one chimeric protein, in said host cell, wherein said chimeric protein comprises: (i) at least one catalytic domain of a capping enzyme, in particular selected in the group consisting of cap-0 canonical capping enzymes, cap-0 non-canonical capping enzymes, cap-1 capping enzymes and cap-2 capping enzymes; and (ii) at least one catalytic domain of a DNA-dependent RNA polymerase, in particular a bacteriophage DNA-dependent RNA polymerase, (b) constitutively or transiently downregulating the phosphorylation level of subunit a of translation initiation factor eIF2 (eIF2?) in said host cell.

  • Publication number: 20170354706
    Abstract: The invention relates to a hybrid proteinaceous molecule comprising at least two proteins capable of inhibiting the activity of at least one antibiotic, the proteins each having different biochemical properties and being bonded to one another. The hybrid proteinaceous molecule inhibits the activity of a least one antibiotic in order to reduce the intestinal side effects of antibiotics, such as severe diarrhoea caused by the antibiotics, and nosocomial infections secondary to parenteral antibiotic therapy.
