Fig. 2

Graphical representation of distribution of selection pressure in Certatiodactyl Toll-like receptors. The majority of sites are under purifying selection. However positive selection is likely to occur in the ecto-domain (ECD) (brown-highlighted) than the transmembrane (TM) and Toll/Interleukin receptor (TIR) domain. Only TLR2-5 and TLR10 are presented for which clear positional demarcation of all three TLR domains was confidently predicted by SMART using cattle TLR as reference
