  • Repertoire of seven transmembrane receptor domain families across various nematode species identified by hmmscan and pfam is shown (Finn et al. 2011). C. elegans exhibits a dramatic expansion of various subfamilies of these proteins. In contrast, the parasitic species do not display a large number of domains for this class of genes.
