The short transcript of SCN5A encodes a mitochondrial-targeted peptide that supports cardiomyocyte metabolism and may influence heart failure and arrhythmias.
The discovery of the NaV1.5-NT peptide reveals a novel pathway for SCN5A-mitochondrial crosstalk, offering potential new insights into metabolic changes during heart failure and arrhythmias.

APA-mediated regulation of SCN5A produces a short transcript encoding NaV1.5-NT, a novel mitochondrial-targeted peptide that supports cardiomyocyte metabolism. While the precise molecular mechanisms remain unresolved, these findings highlight an unforeseen alternative pathway for expanding SCN5A-mitochondrial crosstalk, with potential implications for metabolic changes in heart failure and arrhythmias.
