Predicted sequences for Atlantic salmon (Salmo salar) slc41a1-3, cnnm1-4 and trpm6-7 transporters were retrieved from the Ssal_v3.1/GCA_905237065.2 genome release. Amino acid sequences from Atlantic salmon, a subset of teleost species representing the diversity of the group, as well as representative species from all other vertebrate groups, were aligned using CLUSTALW in Seaview (http://doua.prabi.fr/software/seaview). Ciona intestinalis and Branchiostoma floridae were used as outgroups.
