Immune response regulatory proteins

摘要

Derivatives of the antigen-nonspecific human glycosylation inhibitor having the amino acid sequence represented by SEQ ID NO:2 which are derived therefrom by conversion of the cystein residue at the 60-position in the amino acid sequence of SEQ ID NO:2 into cystein optionally together with substitution, deletion, insertion or modification of at least one amino acid residue other than the cystein residue at the 60-position and have the immunoregulatory activity of the antigen-nonspecific glycosylation inhibitor.
