Model-free free energy for voltage-gated channels

1 C o m m e n t a r y Models have a habit of clinging to the boot-soles of ion channel biophysicists. Our primary electrophysiological recordings displayed in the Results section almost always presage a Discussion section replete with multi-state schemes: gating models, conduction models, hidden Markov models, straightforward models that enlighten , opaque models that obfuscate, heuristic model...

VOLTAGE-GATED ION CHANNELS Voltage-Gated Sodium Channels

Antiepileptic drugs (AEDs) protect against seizures through interactions with a variety of cellular targets. By affecting the functional activity of these targets, AEDs suppress abnormal hypersynchronous activity in brain circuits, leading to protection against seizures. The actions on these targets can be categorized into four broad groups: (i) modulation of voltage-gated ion channels, includi...

Estimating the voltage-dependent free energy change of ion channels using the median voltage for activation

Voltage-gated ion channels are crucial for electrical activity and chemical signaling in a variety of cell types. Structure-activity studies involving electrophysiological characterization of mutants are widely used and allow us to quickly realize the energetic effects of a mutation by measuring macroscopic currents and fitting the observed voltage dependence of conductance to a Boltzmann equat...

Voltage-Gated Sodium Channels Modulation by Bothutous Schach Scorpion Venom

Buthotus schach is one of the dangers scorpion in Iran that belong to the Buthidae family. Toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. In the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...
