Phylogenetic tree of the zebrafish IntFil proteins superimposed on the mouse phylogenetic tree. Names of zebrafish proteins are in red font, mouse proteins in black font. The same procedures were carried out here, as described in the Fig. 1 legend. The IntFil protein names are listed in the first column. “M-” or “Z-” precedes mouse and zebrafish IntFils, respectively. Abbreviations are the same as Figs. 2 and 3. Known isoforms of mouse lamins and synemins are denoted by yellow boxes. The zebrafish’s KRT1-c5, KRT1-19d, and KRT1-c19e are keratin type I gene c5, 19d, and c19e respectively (they are not keratin 1)
