A calcium channel is an ion channel which shows selective permeability to calcium ions. It is sometimes synonymous with voltage-gated calcium channel, [1] which are a type of calcium channel regulated by changes in membrane potential. Some calcium channels are regulated by the binding of a ligand.
P-type calcium channel ("Purkinje") /Q-type calcium channel: HVA (high voltage activated) Ca v 2.1 : α 2 δ, β, possibly γ: Purkinje neurons in the cerebellum / Cerebellar granule cells: N-type calcium channel ("Neural"/"Non-L") HVA (high voltage activated) Ca v 2.2 : α 2 δ/β 1, β 3, β 4, possibly γ: Throughout the brain and peripheral ...
Calcium channel blocker toxicity is the taking of too much of the medications known as calcium channel blockers (CCBs), either by accident or on purpose. [3] This often causes a slow heart rate and low blood pressure . [ 1 ]
Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists [2] are a group of medications that disrupt the movement of calcium (Ca 2+) through calcium channels. [3] Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension.
Voltage-gated sodium channel or. voltage-dependent calcium channel (calciumopathy) Lambert–Eaton myasthenic syndrome: Voltage-gated calcium channel Long QT syndrome main type Romano-Ward syndrome: various, by type Malignant hyperthermia: Ligand-gated calcium channel Mucolipidosis type IV: Non-selective cation channel Myotonia congenita
An L-type calcium channel with its subunits labeled along with some drugs known to inhibit the channel. The L-type calcium channel (also known as the dihydropyridine channel, or DHP channel) is part of the high-voltage activated family of voltage-dependent calcium channel. [2] "L" stands for long-lasting referring to the length of activation.
Studies have shown that the intrathecal injection of the calcium channel inhibitor ziconotide, to block the N-type calcium channels, have produced alleviation of intractable pain. [12] Blockade of the N-type calcium channel is a potential therapeutic strategy for the treatment of alcoholism. Because prolonged alcohol exposure over time has been ...
When calcium ions (Ca 2+) are depleted from the endoplasmic reticulum (a major store of Ca 2+) of mammalian cells, the CRAC channel is activated to slowly replenish the level of calcium in the endoplasmic reticulum. The Ca 2+ Release-activated Ca 2+ (CRAC) Channel (CRAC-C) Family (TC# 1.A.52) is a member of the Cation Diffusion Facilitator (CDF ...
