NCIt definition : A synthetic peptide consisting of amino acid residues 614 through 622 of the melanoma-melanocyte
antigen glycoprotein 100 (gp100). Vaccination with gp100:614-622 peptide may stimulate
a cytotoxic T-cell immune response against tumor cells that express this antigen,
resulting in decreased tumor growth and cell lysis. gp100 antigen is a self-antigen
expressed by melanocytes, pigmented retinal cells and most melanoma lesions and recognized
via class I and II HLA-restricted mechanisms.;
