The present invention discloses that the normal melanogenic gene, gp75 gene, encodes a gene product, a 24 amino acid peptide of ORF3, which is processed to an antigenic cancer peptide recognized by T lymphocytes. The cancer peptide of the invention derived from ORF3 is recognized by cancer antigen specific T lymphocytes as a tumor rejection antigen. The present invention relates to the identification of a second tumor antigen recognized by an HLA- A31 restricted CTL clone derived from the TIL586 cell line. This antigen derived from the TRP-2 protein tumor antigen and peptides thereof are capable of sensitizing target cells for lysis by a CTL clone at 1 nM peptide concentration. Modified peptides were also recognized by the CTL clone. The products of these genes are promising candidates for immunotherapeutic strategies for the treatment and diagnosis of patients with cancer.
