Patent ID: 8536116

Claim:
A modified chemokine peptide which is used as an antagonistic peptide for a chemokine receptor, including an amino acid sequence having an N-terminus, the amino acid sequence comprising: a glutamate (E)-leucine (L)-arginine (R) characteristic sequence situated at the N-terminus of the chemokine peptide; and a modified sequence situated at a region represented as X 5 X 4 X 3 X 2 X 1 -Cys 3 from N-terminus to C-terminus, wherein the Cys 3 is a third cysteine (Cys 3 ) from the N-terminus, wherein X 1 is an aromatic amino acid, an hydrophobic amino acid or a long-chain amino acid, X 2 is glutamine (Q), X 3 is serine (S), X 4 is alanine (A), X 5 is proline (P), and the length of the modified chemokine peptide is 70-107 amino acids.
