Background: Sodium channels underlie neuronal excitability and are regulated by seizures. Results: Mass spectrometric analysis of brain sodium channels revealed novel phosphorylation and methylation sites that decreased and increased, respectively, after seizures. Inducing methylation increased sodium channel activity. Conclusion: Reciprocal phosphorylation and methylation after seizures will alter sodium channel function. Significance: Such regulation would impact neuronal excitability. © 2014 by The American Society for Biochemistry and Molecular Biology, Inc.
