<P>PROBLEM TO BE SOLVED: To provide a highly stabilized MHC class II protein. <P>SOLUTION: In recombinant polypeptide served as α or β subunit of human MHC class II molecule, intermolecular interaction between at least one substituted amino acid introduced to a position outside a peptide-binding groove and peripheral amino acid is strengthened, whereby the stability of the human MHC class II molecule containing the recombinant polypeptide is improved as compared to the human MHC class II molecule constituted by the wild type α or β subunit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
