Identity of Kv3 family members in zebrafish. Two Kv3.3 (kcnc3a, kcnc3b), two Kv3.1 (kcnc1a, kcnc1b), and one each Kv3.2 (kcnc2) and Kv3.4 (kcnc4) genes were identified using the program PhyML [22, 23]. Zebrafish sequences (labeled in red) were aligned with Kv3 sequences from the following species: h, human; m, mouse; Xen, Xenopus laevis; Apt, Apteronotus leptorhynchus (another teleost fish). The alignment and accession numbers for each non-zebrafish sequence are provided in additional file 1, Fig. S1. Numbers on the tree indicate the percentage of trees that contained the labeled node. The scale bar indicates 0.09 substitutions per amino acid residue.
