The α subunit of the cardiac voltage-gated sodium channel, Naᵥ1.5, provides the rapid sodium inward current that initiates cardiomyocyte action potentials. Here, we analyzed for the first time the post-translational modifications of Naᵥ1.5 purified f...

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...

A Missense Mutation in the Sodium Channel β2 Subunit Reveals SCN2B as a New Candidate Gene for Brugada Syndrome (2013)
Journal Article
Riuró, H., Beltran-Alvarez, P., Tarradas, A., Selga, E., Campuzano, O., Vergés, M., Pagans, S., Iglesias, A., Brugada, J., Brugada, P., Vázquez, F. M., Pérez, G. J., Scornik, F. S., & Brugada, R. (2013). A Missense Mutation in the Sodium Channel β2 Subunit Reveals SCN2B as a New Candidate Gene for Brugada Syndrome. Human Mutation, 34(7), 961-966. https://doi.org/10.1002/humu.22328

Brugada Syndrome (BrS) is a familial disease associated with sudden cardiac death. A 20%-25% of BrS patients carry genetic defects that cause loss-of-function of the voltage-gated cardiac sodium channel. Thus, 70%-75% of patients remain without a gen...

Brugada syndrome (BrS) is a life-threatening, inherited arrhythmogenic syndrome associated with autosomal dominant mutations in SCN5A, the gene encoding the cardiac Na+ channel alpha subunit (Nav1.5). The aim of this work was to characterize the func... Read More about A Novel Missense Mutation, I890T, in the Pore Region of Cardiac Sodium Channel Causes Brugada Syndrome.

The cardiac sodium channel is post-translationally modified by arginine methylation (2011)
Journal Article
Beltran-Alvarez, P., Pagans, S., & Brugada, R. (2011). The cardiac sodium channel is post-translationally modified by arginine methylation. Journal of Proteome Research, 10(8), 3712-3719. https://doi.org/10.1021/pr200339n

The α subunit of the cardiac sodium channel (Na v1.5) is an essential protein in the initial depolarization phase of the cardiomyocyte action potential. Post-translational modifications such as phosphorylation are known to regulate Na v1.5 function....

Sudden cardiac death is a major contributor to mortality in industrialized nations; in fact, it is the cause of more deaths than acquired immune deficiency syndrome, lung and breast cancer, and stroke together. Frequently, the autopsy becomes the pri... Read More about Genetics and cardiac channelopathies.

Molecular Systems Biology, 6(1), Article 430. https://doi.org/10.1038/msb.2010.87

Proteing-metabolite networks are central to biological systems, but are incompletely understood. Here, we report a screen to catalog proteing-lipid interactions in yeast. We used arrays of 56 metabolites to measure lipid-binding fingerprints of 172 p... Read More about A systematic screen for proteing-lipid interactions in Saccharomyces cerevisiae.
