Figure 5

A discriminatory indel supports relationships of neuroserpin and homologs from sea urchins, lancelets, and Nematostella. Human representatives of vertebrate serpin groups 1, 3, and 5 containing the indel (marked in red), and from groups 2, 4 and 6 that lack the indel, are shown. The numbering of positions shown above the alignment refers to the sequence of mature human α1-antitrypsin. Positions conserved in at least 70% of sequences are represented in white-on-black printing.
