Conservation of LON-8 in nematodes. Alignment of the predicted LON-8 sequence from five Rhabditid nematode species. C. elegans, C. briggsae and the closely related vertebrate parasitic Strongyloid nematode Haemonchus contortus belong to the family of Rhabditine nematodes. Parastrongyloides trichosuri and Meloidogyne incognita are more distantly related Tylenchine nematodes. The site of cleavage of the predicted signal peptides is indicated.
