Uman KCNJ2. These two transcripts will be further investigated while the remaining three genes were not studied further. Primers spanning the entire coding region of the kcnj2-3 #1 and kcnj2-12 transcripts were designed to confirm the sequences as well as the expression of these genes in the zebrafish heart. No PCR amplicons were obtained using the kcnj2-3 #1 primers, suggesting that the gene may
