This article will address SCN1B from a broad and detailed perspective, with the aim of providing the reader with a complete overview of the topic in question. Different related aspects will be analyzed, such as its origin, evolution, repercussions and possible future challenges. Likewise, various opinions and approaches will be explored with the purpose of offering a comprehensive and balanced vision. Through a journey through the different points of view and relevant studies, this article will seek to provide the reader with a deep and enriching understanding of SCN1B.
Sodium channel subunit beta-1 is a protein that in humans is encoded by the SCN1Bgene.
Voltage-gated sodium channels are essential for the generation and propagation of action potentials in striated muscle and neuronal tissues. Biochemically, they consist of a large alpha subunit and 1 or 2 smaller beta subunits, such as SCN1B. The alpha subunit alone can exhibit all the functional attributes of a voltage-gated Na+ channel, but requires a beta-1 subunit for normal inactivation kinetics.
