This is a reverse transcriptase (RT) epitope (Pol residues 476-484). Within HIV-1 RT the peptide appears to be the dominant HLA A*0201-restricted epitope. Was used to investigate possible mechanisms behind HIV-1 escape from CTL. IV9 is the actual epitope processed and presented in HIV-1-infected cell lines.
