Phylogenetic tree of ABCA proteins in four eukaryotic genomes. Predicted amino acid sequences were aligned using ClustalX, and the alignment used to generate a phylogenetic tree using the neighbour joining method [74]. Bootstrapping was used to determine the relative support of the various branches (5,000 replicates, support expressed as percent) [74]. Dp, Daphnia pulex,; Dm Drosophila melanogaster; Ce Caenorhabditis elegans, h Homo sapiens; Sc Saccharomyces cervisia.
