Fig. 6From: Comparative genomic analysis suggests that the sperm-specific sodium/proton exchanger and soluble adenylyl cyclase are key regulators of CatSper among the MetazoaSynteny block comparison of SLC9B (NHA) and distribution of genes encoding CatSper, sNHE and sAC in vertebrates. Synteny blocks around SLC9B1 (NHA1) and SLC9B2 (NHA2) among human, chicken, frog, medaka, zebrafish, and lizard are shown together with distributions of genes encoding CatSper (black), sNHE (blue) and sAC (red). In synteny blocks, the arrangement reflects the order and orientation of genes in each chromosome. Chromosomes (Chr) are not represented to the scale of base-pair lengthBack to article page
