Mexiletine activates SCN5A-N406K. 2 / 2
| 2

reach
"We discovered mexiletine could elevate the reduced peak sodium current and inhibit the increased late sodium current at the same time, and partially restore the function of SCN5A N406K mutant channel with a mixed biophysical phenotype."

reach
"The decrease in cell surface expression caused by SCN5A N406K mutants was reversed by mexiletine, further supporting the hypothesis that mexiletine could increase the peak I Na of SCN5A N406K mutation through rescuing the trafficking defect of SCN5A-N406K."
