Multiple sequence alignment of IGc1 domains.

<p>The alignment consists of IGc1 domain sequences from organisms of various taxa such as Eutheria, Marsupials, Monotremes, Avians, Chondrichthyes fish and Actinopterygii fishes. Lca is the <i>L. calcarifer</i> protein sequence and the conserved residues are marked by (*). S1, S2, S3, S4, S5, S6 and S7 indicate the regions of seven β strands in the IGc1 domain. Numbers at the top indicate amino acid positions. Information on the sequences is given in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0013159#pone-0013159-t001" target="_blank">Table 1</a>.
