CXorf26 is strongly evolutionary conserved, with conservation found in Batrachochytrium dendrobatidis. A multiple sequence alignment of 20 orthologous protein sequences reveals very strong conservation of the polysaccharide biosynthesis domain, but conservation after it was essentially non-existent in invertebrates. For those vertebrates that contained a sequence after the conserved domain, it was found to be of low complexity and filled with repetitive sequence of the amino acid motif 'GEK', corresponding to amino acids glycine, glutamic acid, and lysine. Glutamic acid and lysine both are charged, which contributes to the overall hydrophilicity of the section after the conserved domain.
