Voltage sensors have been well studied in voltage-gated ion channels for neuronal excitation and muscle contraction. The recent discovery of a voltage-sensing phosphatase, VSP, has changed the idea that voltage sensors are unique to ion flux through membranes. Recent findings on mechanisms and potential applications of VSP are reviewed.
电压传感器在用于神经元兴奋和肌肉收缩的电压门控离子通道中已得到充分研究。最近发现的一种电压感应磷酸酶VSP,改变了电压传感器仅存在于跨膜离子通量中的观点。本文综述了关于VSP的作用机制和潜在应用的最新研究结果。
