PURPOSE: A mutation in the β(1) subunit of the voltage-gated sodium (Na(V)) channel, β(1) (C121W), causes genetic epilepsy with febrile seizures plus (GEFS+), a pediatric syndrome in which febrile seizures are the predominant phenotype. Previous st

Two mutations associated with idiopathic ventricular fibrillation (IVF) are localized within extracellular loops between segments DIIIS1-S2 (R1232W) and DIVS3-S4 (T1620M) of the human cardiac sodium channel (hNav1.5) alpha-subunit. We studied wild-ty

Slow inactivation determines the availability of voltage-gated sodium channels during prolonged depolarization. Slow inactivation in hNa V 1.4 channels occurs with a higher probability than hNa V 1.5 sodium channels; however, the precise molecular me

Slow inactivation in voltage-gated sodium channels is a biophysical process that governs the availability of sodium channels over extended periods of time. Slow inactivation, therefore, plays an important role in controlling membrane excitability, fi

Skeletal and heart muscle excitability is based upon the pool of available sodium channels as determined by both fast and slow inactivation. Slow inactivation in hH1 sodium channels significantly differs from slow inactivation in hSkM1. The beta(1)-s

Genetic epilepsy with febrile seizures plus (GEFS+) is a multifaceted pediatric epilepsy syndrome of which febrile seizures (FS) are one of the most common symptoms. A cysteine to tryptophan substitution at position 121 (C121W) in β1 subunit of NaV

The effects on slow inactivation (SI) of charge substitutions, neutralizations, and reversals were studied for the negatively charged residues D1309 and EE1314,15 surrounding the IFM motif in the DIII–DIV cytoplasmic linker – the putative fast in

Brain sodium channels play a crucial role in neuronal excitability. Ischemia leads to decreased sodium influx that, as suggested by previous studies, may be caused by channel protonation. Using whole-cell recordings we studied effects of low extracel
