... end of the gene, where the zebrafish and human sequences appear to be quite diverse. Together with the well-conserved gene organization, there is a conservation of synteny between the human and zebrafish ... domain and SH2 domain of stat6, and the zinc-finger domain, leucine-zipper domain and fork-head domain of foxp3. In addition, for stat6 and foxp3, there were a few othe...

... [20]. The role of SREBP-1a in the regulation of cell growth and the cell cycle might be biphasic and complex, and needs to be further investigated. SREBP is evolutionarily conserved; however, the key ... inward- rectifying potassium channel, and results in an acetylcholine-sensitive atrial potassium current.
