Transcriptional regulation of the sodium channel gene (SCN5A) by GATA4 in human heart (2016)
Journal Article
Tarradas, A., Pinsach-Abuin, M., Mackintosh, C., Llorà-Batlle, O., Pérez-Serra, A., Batlle, M., …Pagans, S. (2017). Transcriptional regulation of the sodium channel gene (SCN5A) by GATA4 in human heart. Journal of Molecular and Cellular Cardiology, 102, 74-82. https://doi.org/10.1016/j.yjmcc.2016.10.013

Aberrant expression of the sodium channel gene (SCN5A) has been proposed to disrupt cardiac action potential and cause human cardiac arrhythmias, but the mechanisms of SCN5A gene regulation and dysregulation still remain largely unexplored. To gain i... Read More about Transcriptional regulation of the sodium channel gene (SCN5A) by GATA4 in human heart.

Protein arginine methyl transferases-3 and -5 increase cell surface expression of cardiac sodium channel (2013)
Journal Article
Beltran-Alvarez, P., Espejo, A., Schmauder, R., Beltran, C., Mrowka, R., Linke, T., …Brugada, R. (2013). Protein arginine methyl transferases-3 and -5 increase cell surface expression of cardiac sodium channel. FEBS Letters, 587(19), 3159-3165. https://doi.org/10.1016/j.febslet.2013.07.043

The α-subunit of the cardiac voltage-gated sodium channel (Na V1.5) plays a central role in cardiomyocyte excitability. We have recently reported that NaV1.5 is post-translationally modified by arginine methylation. Here, we aimed to identify the enz...
