p53-derived peptide of GLAPPQHLIRV sequence covering 187-197 and HLA-A*02:01) molecule. The peptide p53 187-197 recognizes human CD8 T cells, and can be used in the analysis of individual antigen-specific T cells. GLAPPQHLIRV is a linear peptidic epitope (epitope ID20767) studied as part of Cellular tumor antigen p53 from Homo sapiens (human) and Cellular tumor antigen p53 from Otospermophilus beecheyi (California ground squirrel). This epitope has been studied for immune reactivity, tested in T cell assays and MHC ligand assays
