Figure S2. Heptad repeats along the three coiled coil domains of the isomin molecule. The (abcdefg) positions of consecutive heptads are reported above the isomin aminoacid sequence; coiled coil domains are highlighted in grey. The arrowhead indicates the position of the stutter. The heptad positions and the ends of the coiled coil domains were inferred by comparison of the secondary structure prediction results with the sequence alignment of isomin and other invertebrate intermediate filament proteins.
