Figure 2From: An unexpectedly high degree of specialization and a widespread involvement in sterol metabolism among the C. elegans putative aminophospholipid translocasesA phylogenetic tree of S. cerevisiae , C. elegans and human P-type ATPases in subfamily IV. The tree was assembled using ClustalW2 [48]. The outgroup is a Drosophila melanogaster calcium-transporting P-type ATPase.Back to article page
