Structural and Evolutionary Adaptation of NOD-Like Receptors in Birds

Figure 3

Location of positively selected sites of four NLR molecules in birds. Protein architectures were generated with PROSITE MyDomains image creator tool (http://www.expasy.org/tools/mydomains/). Red bars indicate adaptive amino acid substitutions. Colored areas represent different conserved domains (blue, CARD or PYD domain; green, NACHT domain; orange, LRR domain).
