    摘要: The present disclosure relates to modified proteins and peptides that have reduced ability to bind to pre-existing antibodies. Such modified protein/peptide molecules can comprise C-terminal additions, extensions or tags and/or certain amino acid substitutions. Such modified molecules (e.g., fusions and conjugates) comprise proteins, peptides, antigen binding molecules, antibodies or antibody fragments such as single variable domains. The disclosure further relates to uses and formulations of compositions comprising such modified C-terminally extended and/or amino acid substituted molecules and also to methods of production and expression of these.

    摘要: Cat C3d polypeptide, fragments thereof, and nucleic acid sequences encoding the polypeptide and fragments are described. Genetic constructs encoding such polypeptides can be used to enhance the immunogenicity of antigens in cats. Variant nucleic acid sequences encoding cat C3d polypeptides, when used to express tandem arrays of the polypeptide show enhanced stability, leading to high level expression in eukaryotic and prokaryotic cell expression systems. When incorporated into a DNA immunization vector or a recombinant live organism vaccine, the variant sequences have reduced risk of undergoing homologous recombination with genomic DNA compared to wild-type sequences, thus reducing the risk of potentially damaging integration events.
