Multiple sequence alignment of rusticalin-like proteins. Predicted signal peptides were trimmed out before alignment. Note the perfect match and conservation of cysteine residues highlighted in yellow. N- and C-terminal domains of rusticalin-like proteins are shown in black. Note the lack of 40 C-terminal residues in rusticalin. The tentative linker region between N- and C-terminal domains is shown in gray. Two cysteine-rich repeats inside the N-terminal domain are shown in blue. Amino acid residues above 85% identity threshold are colored according to their physicochemical properties. Styru – Styela rustica, Bosch – Botryllus schlosseri, Cioin – Ciona intestinalis, Ciosa – Ciona savignyi, Dipli – Diplosoma listerianum, Oikdi – Oikopleura dioica, Brafl – Branchiostoma floridae, Alvja – Alveopora japonica, Triad – Trichoplax adhaerens
