Abstract
The invention relates generally to chaperonin 10 N-terminal variants. More specifically, the invention relates to chaperonin 10 N-terminal variants with enhanced immunomodulatory capacity and/or enhanced binding affinity for pathogen-associated molecular patterns (PAMPs) and/or damage-associated molecular patterns (DAMPs).
Claims20
-23. (canceled)
An isolated chaperonin 10 (Cpn10) variant polypeptide sharing at least 90% sequence identity with a wild-type Cpn10 polypeptide and comprising an N-terminus extended by at least two additional amino acid residues compared to said wild-type polypeptide, wherein the polypeptide has increased binding affinity for a pathogen-associated molecular pattern (PAMP) compared to the binding affinity of Ala-Cpn10 (SEQ ID NO:
- 3) for said PAMP.
An isolated chaperonin 10 (Cpn10) variant polypeptide sharing at least 70% sequence identity with a wild-type Cpn10 polypeptide and comprising an N-terminus extended by one additional amino acid residue compared to said wild-type polypeptide, wherein said additional amino acid residue is a serine or proline residue, and wherein said variant polypeptide has increased immunomodulatory function compared to human Ala-Cpn10.
