Of the KCNJ4 gene family and is the apparent orthologue of KCNJ4. Both kcnj2-3 #2 and kcnj2-24 are in the fish clade3. Results and Discussion3.1. Bioinformatic Analysis of Zebrafish Orthologues of the Human KCNJ2 Gene. Several putative zebrafish orthologues of human KCNJ2 gene can be found on the Ensembl Genome4 of the KCNJ12 family and are coorthologues of the human KCNJ12 gene. To confirm the co
