Tumor antigen protein art-1 and tumor antigen peptide thereof

An isolated tumor antigen peptide consisting of 8 to 14 amino acids that is a fragment of the amino acid sequence of SEQ ID NO:

• 1, which fragment comprises a sequence selected from an amino acid sequence shown in any one of SEQ ID NOs:
• 3–18, or an isolated tumor antigen peptide consisting of 8 to 14 amino acids that is a fragment of the amino acid sequence of SEQ ID NO:
• 1, which comprises a sequence selected from an amino acid sequence shown in any one of SEQ ID NOs:
• 3–18 wherein the amino acid residue at position 2 is substituted by tyrosine, phenylalanine, methionine, or tryptophan, and/or the C-terminus is substituted by phenylalanine, leucine, isoleucine, tryptophan, or methionine, and which binds to an HLA antigen and is recognized by cytotoxic T lymphocytes.
