Figure 2From: The efficiency of Vpx-mediated SAMHD1 antagonism does not correlate with the potency of viral control in HIV-2-infected individualsAlignment of HIV-2 and SIV Vpx sequences. The HIV-2 ROD Vpx sequence is shown on top for comparison. The three putative α-helical regions, the nuclear localization signal (NLS), residue Q76 involved in DCAF1 binding, and the C-terminal proline-rich region are indicated. Dots indicate amino acid identity.Back to article page
