Figure 7From: The distribution of CTL epitopes in HIV-1 appears to be random, and similar to that of other proteomesAn overlay of HIV-1 proteins on top of the human proteome. The degree of clustering of CTL epitopes in proteins is determined by the H&S index and plotted against protein length. Significantly clustered sequences are denoted in yellow dots for the human proteome, and in red dots for HIV-1 (p < 0.001, permutation test). The index scores of HIV-1 fall within the range found in human proteomes, suggesting that the epitope distribution pattern of HIV-1 is not extraordinary.Back to article page
