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.
Gating (electrophysiology) An animated representation of the molecular structure of a simple ion channel. In electrophysiology, the term gating refers to the opening ( activation) or closing (by deactivation or inactivation) of ion channels. [ 1] This change in conformation is a response to changes in transmembrane voltage.
Doina and Ion Aldea Teodorovici. Doina and Ion Aldea Teodorovici was a Moldovan musical duo consisting of married couple Doina and Ion Aldea Teodorovici. The group disbanded in 1992, after both members died in a road traffic accident in Coșereni. Today, there is a monument to them there, [ 1][ 2] as well as another in Chișinău. [ 3][ 4]
Phosphatidylinositol 4,5-bisphosphate (PIP 2) was the first and remains the best studied lipid to gate ion channels. PIP 2 is a cell membrane lipid, and its role in gating ion channels represents a novel role for the molecule. K ir channels: PIP 2 binds to and directly activates inwardly rectifying potassium channels (K ir).
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.
The interplay between opening and inactivation controls the firing pattern of a neuron by changing the rate and amount of ion flow through the channels. Voltage-gated ion channels open upon depolarization of the cell membrane. This creates a current caused by the flow of ions through the channel. Shortly after opening, the channel is blocked by ...
