Since its initial cloning in 1992, SCN5A (Nav1.5) has become known as “the” cardiac sodium channel.1 SCN5A encodes a tetrodotoxin (TTX)-resistant channel that is responsible for the inward sodium current (INa), which initiates the cardiac action potential. Its RNA and protein expression dominate the sodium channel landscape in the ventricle, atrium, and specialized conduction system. Mice heter...

The small GTP-binding protein Arf6 is known to be an important regulator of the actin cytoskeleton and of cell motility associated with metastasis. A recent study identifies yet another role for Arf6 in metastasis - as a regulator of plasma-membrane-derived microvesicle release.
