Interplay between R513 methylation and S516 phosphorylation of the cardiac voltage-gated sodium channel (2014)
Journal Article
Beltran-Alvarez, P., Feixas, F., Osuna, S., Díaz-Hernández, R., Brugada, R., & Pagans, S. (2015). Interplay between R513 methylation and S516 phosphorylation of the cardiac voltage-gated sodium channel. Amino acids, 47(2), 429-434. https://doi.org/10.1007/s00726-014-1890-0

Arginine methylation is a novel post-translational modification within the voltage-gated ion channel superfamily, including the cardiac sodium channel, Naᵥ1.5. We show that Naᵥ1.5 R513 methylation decreases S516 phosphorylation rate by 4 orders of ma...

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...

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., Batlle, M., Pérez-Villa, F., Pérez, G. J., Scornik, F. S., Benndorf, K., Pagans, S., Zimmer, T., & Brugada, R.

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)

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.
