  2. Sodium channel - Wikipedia

    en.wikipedia.org/wiki/Sodium_channel

    The family of sodium channels has 9 known members, with amino acid identity >50% in the trans-membrane segments and extracellular loop regions. A standardized nomenclature for sodium channels is currently used and is maintained by the IUPHAR. [11] The proteins of these channels are named Na v 1.1 through Na v 1.9.

  3. Voltage-gated sodium channel - Wikipedia

    en.wikipedia.org/wiki/Voltage-gated_sodium_channel

    Voltage-gated sodium channels (VGSCs), also known as voltage-dependent sodium channels (VDSCs), are a group of voltage-gated ion channels found in the membrane of excitable cells (e.g., muscle, glial cells, neurons, etc.) with a permeability to the sodium ion Na +. They are the main channels involved in action potential of excitable cells.

  4. Gating (electrophysiology) - Wikipedia

    en.wikipedia.org/wiki/Gating_(electrophysiology)

    Deactivation is the return of an ion channel to its closed conformation. For voltage-gated channels this occurs when the voltage differential that originally caused the channel to open returns to its resting value. [31] In voltage-gated sodium channels, deactivation is necessary to recover from inactivation. [26]

    A positively charged region between the III and IV domains of sodium channels is thought to act in a similar way. [9] The essential region for inactivation in sodium channels is four amino acid sequence made up of isoleucine, phenylalanine, methionine and threonine (IFMT). [13] The T and F interact directly with the docking site in the channel ...

  9. Nav1.4 - Wikipedia

    en.wikipedia.org/wiki/Nav1.4

    In hypokalemic periodic paralysis, arginine residues making up the voltage sensor of Na v 1.4 are mutated. The voltage sensor comprises the S4 alpha helix of each of the four transmembrane domains (I-IV) of the protein, and contains basic residues that only allow entry of the positive sodium ions at appropriate membrane voltages by blocking or opening the channel pore.
