Multiple amino acid sequence alignment of the bovine SERPINA3 family. The eight putative bovSERPINA3 proteins were aligned using CLUSTALW . Numberings refer to position in the alignment, above the sequences, and to the length of each sequence, at the end of the line. Dot indicates a common residue with that of the first sequence (bovSERPINA3-1), dash shows a gap, i.e. a position with an insertion-deletion event. Shaded characters indicate selectively conserved residues specific of the sub-group including bovSERPINA3-7 and bovSERPINA3-8. (▼) indicates asparagine (N) residue involved in a potential N-glycosylation site.
