Multiple sequence alignment of PRV σ1 with MRV T3D σ1.

Abstract

<p>Black lines represent putative nuclear export signals (NEP) in MRV and PRV, respectively, as predicted by NetNes 1.1. ▪ = L₁₄₉ in the MRV protein involved in a second predicted NES. ▴ = residues in the MRV protein involved in binding to sialic acid residues. The alignment has been manually adjusted.</p
