A. Schematic models of the six tenascin paralogs of the zebrafish Danio rerio (TNCa, XP_021332057; TNCb, NP_001299845; TNR, NP_919364; TNW, CAA04755; TNX19, XP_021323869; TNX16, XP_021322558). The N-terminal region of TNX16 includes many copies of an approximately 60-amino acid long repeat (with the sequence KEQTQST most highly conserved) between the signal peptide and the coiled-coil-forming heptad repeats. B. The domain architecture of a TNX from the common carp Cyprinus carpio. C. Sequence alignment of 180 amino acids from the repeat region of the C. carpio TNX with the same region in D. rerio TNX16. The highly conserved amino acids selected to represent the repeat are shown in bold
