From: Phylogenetic analysis of the tenascin gene family: evidence of origin early in the chordate lineage
A tenascin phylogenetic tree. The amino acid sequences of the FReDs from urochordate, fish, amphibian and mammalian tenascins were used to construct an unrooted molecular phlyogenetic tree. The numbers at the internal nodes are the probability that each branch point is correct. The scale represents 0.100 expected changes. The tree reveals that there are four members of the tenascin family in vertebrates: tenascin-X, tenascin-W, tenascin-C and tenascin-R.
