InterPro. The cation channels of sperm also known as Catsper channels or CatSper, are ion channels that are related to the two-pore channels and distantly related to TRP channels. The four members of this family form voltage-gated Ca 2+ channels that seem to be specific to sperm. As sperm encounter the more alkaline environment of the female ...
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.
Voltage-gated ion channels are a class of transmembrane proteins that form ion channels that are activated by changes in a cell's electrical membrane potential near the channel. The membrane potential alters the conformation of the channel proteins, regulating their opening and closing. Cell membranes are generally impermeable to ions, thus ...

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.
Dependent on type. Include: Sudden death. Channelopathies are a group of diseases caused by the dysfunction of ion channel subunits or their interacting proteins. These diseases can be inherited or acquired by other disorders, drugs, or toxins. Mutations in genes encoding ion channels, which impair channel function, are the most common cause of ...
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.
