The SCN3B protein critically affects sodium channel dynamics, inducing unique sustained currents and slower inactivation rates compared to beta-1. Its interaction with NFASC is shown to guide sodium channels to the nodes of Ranvier during axonal development and retain them in mature myelinated axons. SCN3B Protein, Human (HEK293, His) is the recombinant human-derived SCN3B protein, expressed by HEK293 , with C-His labeled tag.
