Lukacs et al. BMC Genomics 2010, 11:154 http://www.biomedcentral.com/1471-2164/11/154 Page 11 of 17 Figure 5 Alignment of Atlantic salmon MHC class I sequences. Comparison of Atlantic Salmon UBA*0301 [Genbank: AAN75116], UBA*1001 [Genbank: AAN75118], ULA [Genbank: ABQ59666], UGA, UDA, UHA1, UHA2, ZAA, ZBA, ZCA, SAA (described in this paper), LBA [Genbank: DY733800 and GO062643] and HLA-A2 [Genbank: AAA76608]. Dots indicate identities, dashes indicate gaps or missing sequence information. Cysteine residues involved in putative Ig fold are marked ♦ above sequences. Anchor residues known to bind the ends of peptide are marked # based on mammalian positions. Unique N-linked glycosylation sites are marked ! and CD8 binding site are boxed based on the acidic stretch from mammalian. b defines Z, S, L and UHA residues potentially involved in interactions with a different beta2-microglobulin. Individual domains/exon for LBA are based on the Sasa- UBA*0301 sequence.
