We show that sodium channels with the missense mutation recover from inactivation more rapidly than normal and that the frameshift mutation causes the sodium channel to be non-functional.

电生理研究显示含有错义突变的钠离子通道比正常通道从静止中恢复的更快，而读码突变使钠离子通道失去功能。

Jingzhaotoxin-I(JZTX-I), a 33-residue polypeptide with three disulfide bonds, was a novel spider neurotoxin preferentially inhibiting cardiac sodium channel inactivation.

敬钊毒素-I（JZTX-I）是一种能够抑制心肌钠通道失活的新型蜘蛛神经毒素，该文结合高效液相色谱与色氨酸荧光测定技术研究了JZTX-I的磷脂膜结合活性。
