From: Comparative genomic analysis suggests that the sperm-specific sodium/proton exchanger and soluble adenylyl cyclase are key regulators of CatSper among the Metazoa

Fig. 1

Distribution of genes encoding CatSper, sNHE, and sAC in the entire phylogenetic tree of eukaryotes. The tree indicates the metazoan taxonomic groups (green background) and non-metazoan species (purple background). Closed boxes represent the presence of genes encoding each protein: CatSper (black), sNHE (blue) and sAC (red). Taxonomic groups with open boxes have varied gene distributions within the groups (the detailed distributions can be seen in the following figures). Homologues for sNHE and sAC are represented as half-filled boxes, blue and red, respectively. The phylogenetic tree was prepared based on the Tree of Life Web project (http://www.tolweb.org/tree/) with some modifications based on recent reports [93,94,95,96]. The branching patterns do not represent the proportional evolutionary rate
