Fig. 4

Schematic representation of protein conserved domains in platyhelminth TNF ligands. Each gray bar length is proportionally adjusted based on the total number of amino acids residues, the number of amino acid residues is indicated on the right side of each bar. The coordinates of each identified conserved domain are indicated on top (start) and at the bottom (end) of each element. Key: yellow rectangle, transmembrane region; orange hexagon, TNF conserved domain; light orange hexagon, TNF-like domain (belonging to the TNF family)
