Claims (3)

1 . An isolated protein or peptide, wherein said protein or peptide comprises the amino acid sequence of SEQ ID NO: 11 and wherein said protein or peptide is capable of restoring MHC-II expression in a cell from an MHC-II deficiency patient in complementation group B.

2 . The protein or peptide according to claim 1 wherein the MHC-II is HLA-DR, HLA-DP or HLA-DQ.

3 . An isolated protein or peptide comprising an amino acid sequence having at least 95% identity or similarity with the amino acid sequence of SEQ ID NO: 11, wherein said protein or peptide is capable of restoring MHC-II expression in a cell from an MHC-II deficiency patient in complementation group B and wherein said protein or peptide comprises an ankyrin-repeating region having an amino acid sequence comprising amino acid residues 122-222 of SEQ ID NO: 11.
