Fusion polypeptide with variant il-2 and antibody fc region
A recently granted patent (Publication Number: US11905320B2) discloses a fusion polypeptide comprising a variant IL-2 polypeptide with up to five amino acid substitutions and an antibody Fc region. The fusion polypeptide ranges from 300 to 700 amino acids and does not include a major histocompatibility complex (MHC) polypeptide. Additionally, the patent specifies variations in the amino acid sequence of the antibody Fc region, ensuring at least 95% sequence identity to a specific reference sequence (SEQ ID NO: 57) with specific amino acid substitutions.
Furthermore, the patent claims cover fusion polypeptides with different ranges of amino acids, from 300 to 700, and variations in the IL-2 polypeptide with up to four amino acid substitutions. The fusion polypeptides also include a heterologous fusion partner, comprising an antibody Fc region and an antigen-binding region of an antibody. The patent emphasizes the exclusion of major histocompatibility complex (MHC) polypeptides in these fusion polypeptides and highlights the specific amino acid substitutions in the Ig Fc region. Overall, the patent provides a detailed description of the fusion polypeptides, their components, and variations, aiming to protect the intellectual property associated with these novel compositions.
