I'm thankful that you could read & respond to my attempt to understand the mechanics of the voltage gate operation, and I wonder if you could explain how the hydrophobic alanine (residue? Is residue the right word for it?) and the IFM moiety are mutually attracted (in inactivation of the open gate)? I'm guessing that when they're close enough intermolecular forces 'bind' them temporarily, but what attracts them together initially when the alanine is exposed?

Hi, can you tell me is there 1 voltage sensor which is made of four S4 segments? Or there are 4 voltage sensors?
@dannichols6261
3 жыл бұрын
This diagram and explanation is extremely helpful! Thank you for making it! At 6:10 , is it correct to say that sufficient depolarization pushes the voltage sensor outward toward the extracellular environment, and because the voltage sensor is CONNECTED to the activation gate, it PULLS the attached activation gate open, which gate component was blocking the pore which was created by & is between S5 & S6? And that there are FOUR gates or gate sections, one in each of the 4 domains ? And at 6:49, is it correct that as the activation gate swings open, it exposes hydrophobic (residues?) which attract a 'ball' (IFM moiety) on its molecular 'chain' toward it, such that the 'ball' swings into the pore and blocks the bottom of it and inactivates the channel? Could you say in what way the hydrophobic alanine and the IFM moiety are mutually attracted? And presumably when the voltage sensor returns downward when the membrane at that location re-polarizes, it pushes the gate part back into both closure of the pore, and also interferes with the IFM moiety/alanine connection and breaks it, taking the channel out of inactivation?

Yes, your understanding is correct! But, these are theoretical models based on experiments done so far. In future, these models could be updated/revised to incorporate additional findings.

@@ThePhysiologyChannel Thank you, not only for this wonderful animated 'cartoon' which helps me understand the mechanical actions of the gating better than any I've seen before, and for verifying my attempt to understand, but perhaps most importantly for reminding me that these are theoretical models based upon painstaking experiments, which models may need to be improved as time goes by.

Can you explain how the new drug pregablin works that is prescribed to people with epilepsy and who may suffer from anxiety. Those who supply this drug cannot explain the mechanism of this drug - but they suspect that it binds calcium to the alpha 1 gated receptor. Pregabalin is an anticonvulsant drug used for neuropathic pain, epilepsy and generalized anxiety disorder.[4] It presents antihyperalgesic actions by binding to the α2δ subunit of the voltage-dependent calcium channels without presenting antinociceptive actions.[5] Pregabalin is marketed by Pfizer under the trade name Lyrica and Lyrica Cr (extended release).[13] It is considered to have a dependence liability if misused, and is classified as a Schedule V drug in the U.S.[4]

@@ThePhysiologyChannel Morever, given that potassium-gated channels activate upon depolarization, would their sensor be less reactive, in the sense that there has to be a higher positive charge inside the cell in order to cause them to open?
