calcium release channelIn recent years a great deal of evidence has accumulated that demonstrates the large amount of diversity that exists between Ca channels. By Ca channels we mean membrane pores that are opened by depolarization, allow Ca 2+ to flow down its electrochemical gradient when the ...
4.2.4.2 Ca2+ release activated Ca2+ channels of the ORAI family The Ca2+-release activated Ca2+ current (ICRAC) is the principal component of store-operated Ca2+ entry (SOCE) in the majority of non-excitable cells.353 These CRAC channels are assembled (homo- or multimerically354) from thre...

release channel is a macromolecular complex comprised of four ryanodine receptor (RyR) proteins, stabilizing proteins such as FKBP12.6, kinases,phosphatases, and many other proteins includingcalsequestrin,triadin, junctin and junctophilin[28]. L-type calcium channels and SR calcium release channels are...
Definition (CSP) class of drugs that act by selective inhibition of calcium influx through cell membranes or on the release and binding of calcium in intracellular pools; since they are inducers of vascular and other smooth muscle relaxation, they are used in the drug therapy of hypertension and...

The primary event of physiological Ca2+ release, the Ca2+ spark, is the simultaneous opening of multiple channels, the coordinating mechanism of which does not appear to be CICR because of the low probability of CICR opening under physiological conditions. The coordination may require Ca2+, but ...
3.1.3 Voltage-gated calcium channels Voltage-gated calcium channels (CaV) are pore-forming membrane proteins that open in response to membrane depolarisation to permit the influx of calcium ions, which is essential for the regulation of many intracellular processes, including neurotransmitter release. ...
