Phylogenetic analysis of the HML10 subtype II Rec putative proteins. The HML10 subtype II proviruses nucleotide sequences corresponding to a predicted Rec domain were translated and the obtained putative proteins (puteins) were analyzed in a NJ tree including previously reported HERV-K HML2 Rec proteins (black triangles) and the analogues HIV-1 Rev. (white triangle), HTLV-1 Rex (black square) and STLV Rex (white square) proteins. Evolutionary relationships were inferred by using the Neighbor Joining method and the p-distance model. The resulting phylogeny was tested by using the Bootstrap method with 1000 replicates. Length of branches indicates the number of substitutions per site
