Distribution of tektin sequences. Phylogenetic tree showing the relationships between known tektin sequences. The three original sequences obtained from the sea urchin Strongylocentrotus purpuratus are labeled in pink, mammalian tektins 1-3, and 5 in green, and mammalian tektin 4 (found in dense fibers [45]) in blue. Neoptera is a taxonomic group that includes most of the winged insects. Modified output from pfam: family: tektin (pf03148) [66, 67].
