Neuronal Voltage-Gated Calcium Channels: Structure, Function, and Dysfunction
Voltage-gated calcium channels are the primary mediators of depolarization-induced calcium entry into neurons. There is great diversity of calcium channel subtypes due to multiple genes that encode calcium channel α1 subunits, coassembly with a variety of ancillary calcium channel subunits, and alternative splicing. This allows these channels to fulfill highly specialized roles in specific neur...
متن کاملcompactifications and function spaces on weighted semigruops
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
15 صفحه اولNeuronal calcium sparks and intracellular calcium "noise".
Intracellular calcium ions are involved in many forms of cellular function. To accommodate so many control functions, a complex spatiotemporal organization of calcium signaling has developed. In both excitable and nonexcitable cells, calcium signaling was found to fluctuate. Sudden localized increases in the intracellular calcium concentration-or calcium sparks-were found in heart, striated and...
متن کاملPlasma membrane calcium ATPases as critical regulators of calcium homeostasis during neuronal cell function.
The plasma membrane calcium ATPases (PMCAs) are ubiquitously expressed proteins that couple the extrusion of calcium across the plasma membrane with the hydrolysis of ATP. In mammals, four separate genes encode distinct PMCA isoforms. Complex patterns of alternative RNA splicing generate additional isoform variability. Functionally, the PMCAs were originally assigned the role of maintaining bas...

the two membranes are bound together (Rosenbluth, Introduction 1962). Indeed, the two membranes are separated by a Calcium plays an important role in regulating a great fuzzy material with a distinct periodicity reminiscent of variety of neuronal processes. Like other cells, neurons the triadic junction of muscle cells (Henkart et al., 1976). use both extracellular and intracellular sources of ...
