Conservation of NES function across avian retroviral Gag proteins. (A) Sequence alignment of the C-terminal portion of the p10 domain of a collection of alpharetroviruses using MultAlin analysis. The consensus sequence shown underneath the box represents residues of >70% sequence identity, with residues having 100% identity depicted in capital letters. (B) Subcellular localization of wild-type and mutant Gag-GFP proteins expressed in quail fibroblasts in the absence (left panels) or presence (right panels) of 18 nM LMB.
