Fig. 3From: Innate immunity in the simplest animals – placozoansDomain composition of the NOD-like receptor repertoire in Trichoplax sp. H2. The central NOD-domain (NACHT/NB-ARC) is depicted in green. Possible Apaf-1 homologs are shaded in grey, clear homologs are bordered by a dotted line. Numbers represent the count of predicted proteins with the respective domain pattern. See also Additional file 4: Dataset S3DBack to article page
