The kcnn1 gene (SK) was duplicated in zebrafish and teleosts. A, Maximum likelihood phylogeny of zebrafish, human, and mouse KCNN genes. Two zebrafish kcnn1 genes were grouped with human and mouse KCNN1 genes. Branch lengths are proportional to expected replacements per site. B, Maximum likelihood phylogeny of vertebrate KCNN1 proteins with representative vertebrate species. In addition to zebrafish, all analyzed teleost species also have two kcnn1a genes. Both phylogenetic trees were inferred with JTT model plus gamma distances using PhyML program. Numbers around each node indicate bootstrap values based on 1000 replicates
