Major histocompatibility complex class II DOA sequences from three Antarctic seal species verify stabilizing selection on the DO locus

Abstract: To provide additional support for the sequence conservation and hence the regulatory role of the MHC class II DOA locus, we obtained the nucleotide sequences of exon 2 and exon 3, along with the intervening intron, of the Ross seal, and sequences from the exon 2 region from the Weddell and...

Description
Summary:Abstract: To provide additional support for the sequence conservation and hence the regulatory role of the MHC class II DOA locus, we obtained the nucleotide sequences of exon 2 and exon 3, along with the intervening intron, of the Ross seal, and sequences from the exon 2 region from the Weddell and leopard seals. These are the first reports of the sequences of this locus from a carnivore species. The results demonstrate strong conservation among mammals for the exon sequence and produce a gene genealogy that is consistent in topology with a species tree.
