Voltage-gated Na channels are responsible for the Na current that underlies the rapid upstroke of the action potential in nerve and muscle fibres. Mutations in sodium channel genes may therefore be expected to result in diseases of nerve and muscle, including cardiac muscle. In the mutations ...
Voltage-gated Na+ (NaV) channels are key mediators of neuronal function and essential for neuronal excitability. Their abnormal activity is implicated in the generation of seizures, both in acquired and genetic epilepsy. Several of the most widely used antiepileptic drugs inhibit NaV activity by ...

Channel proteins (such as the voltage-gated Na channel) transport ions much faster than carrier proteins (such as the Na-K pump), but they cannot be coupled to an energy source; therefore, transport mediated by channels is always passive. A.正确B.错误 相关知识点: 试题来源: 解析 A 反...

Voltage-gated Na(+) channels (VGSC) have been implicated in the metastatic potential of human breast, prostate, and lung cancer cells. Specifically, the SCN5A gene encoding the VGSC isotype Na(v)1.5 has been defined as a key driver of human cancer cell invasion. In this study, we examined...
6a,b). Using Foldseek40, the VSDs in SLC9C1 were surprisingly most similar to VSDIV from the human voltage-gated Na+ channel structure of NaV1.7 in the active up-state41,42 (Fig. 3c). In particular, the S4 segment of SLC9C1 contains six gating-charge residues—Lys800 (K1), Arg803...
Voltage-gated Na(+) channel (Na(v)) 1.8 contributes to the majority of the Na(+) current that underlies the depolarizing phase of action potentials. Na(v)1.8 is mainly distributed intracellularly and its current amplitude can be enhanced by the beta3 subunit. However, little is known about...
