Gp100 (25-33), human is the amino acids 25-33 fragment of the human melanoma antigen. It is a 9-amino acid (AA) epitope restricted by H-2Db and recognized by the T cells.This is amino acids 25 to 33 fragment of human melanoma antigen gp100. This H-2Db restricted epitope is recognized by T cells. The gp100-specific, H-2Db-restricted, CD8+ T cells are capable of recognizing B16 melanoma but not normal melanocytes.
