Abstract excerpt
BACKGROUND: Many homeobox genes show remarkable conservation between divergent animal phyla. In contrast, the ARGFX (Arginine-fifty homeobox) homeobox locus was identified in the human genome but is not present in mouse or invertebrates. Here we ask when and how this locus originated and examine its pattern of molecular evolution. RESULTS: Phylogenetic and phylogenomic analyses suggest that ARGFX originated by...
