Voltage-gated ion channels have a crucial role in excitable cells such as neuronal and muscle tissues, allowing a rapid and co-ordinated depolarization in response to triggering voltage change. Found along the axon and at the synapse, voltage-gated ion channels directionally propagate electrical signals. Voltage-gated ion-channels are usually ...
Ion channels are located within the membrane of all excitable cells, [ 3] and of many intracellular organelles. They are often described as narrow, water-filled tunnels that allow only ions of a certain size and/or charge to pass through. This characteristic is called selective permeability.
Transient receptor potential channel. Transient receptor potential channels ( TRP channels) are a group of ion channels located mostly on the plasma membrane of numerous animal cell types. Most of these are grouped into two broad groups: Group 1 includes TRPC ( "C" for canonical), TRPV ("V" for vanilloid ), TRPVL ("VL" for vanilloid-like), TRPM ...
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.

Two-pore channels (TPCs) are eukaryotic intracellular voltage-gated and ligand gated cation selective ion channels. [1] There are two known paralogs in the human genome, TPC1s and TPC2s. [2] In humans, TPC1s are sodium selective and TPC2s conduct sodium ions, calcium ions and possibly hydrogen ions. Plant TPC1s are non-selective channels.
Synthetic ion channels. Synthetic ion channels are de novo chemical compounds that insert into lipid bilayers, form pores, and allow ions to flow from one side to the other. [1] They are man-made analogues of natural ion channels, and are thus also known as artificial ion channels. Compared to biological channels, they usually allow fluxes of ...
Acid-sensing ion channels ( ASICs) are neuronal voltage-insensitive sodium channels activated by extracellular protons permeable to Na +. ASIC1 also shows low Ca 2+ permeability. [2] ASIC proteins are a subfamily of the ENaC /Deg superfamily of ion channels. These genes have splice variants that encode for several isoforms that are marked by a ...
