A recently granted patent (Publication Number: US11952415B2) discloses a novel polypeptide comprising a scaffold protein sequence with specific mutations and identity criteria. The polypeptide includes a N32G mutation relative to a defined amino acid sequence and has at least 90% identity to the same sequence. Additionally, the polypeptide incorporates two heterologous peptides inserted within the scaffold protein sequence, with specific insertion positions and length requirements. The patent also covers variations of the polypeptide with different mutations and identity percentages, further expanding the scope of the invention.

Moreover, the patent extends to applications involving host cells containing the described polypeptide and fusion proteins incorporating the polypeptide along with additional amino acid sequences like signal sequences, affinity tags, and transmembrane domains. The fusion proteins may also include half-life extension polypeptides, enhancing their stability and functionality. The detailed claims outline the specific mutations, insertion positions, and length constraints for the heterologous peptides, providing a comprehensive framework for the development and utilization of these novel polypeptides and fusion proteins in various biotechnological and therapeutic applications.
