Overview of Voltage-Dependent Calcium Channels [PDF]

open access: possibleJournal of Bioenergetics and Biomembranes, 1998
Voltage-dependent calcium channels couple electrical signals to cellular responses in excitable cells. Calcium channels are crucial for excitation-secretion coupling in neurons and endocrine cells, and excitation-contraction coupling in muscle. Several pharmacologically and kinetically distinct calcium channel types have been identified at the ...

Genetic Analysis of Voltage-Dependent Calcium Channels

Journal of Bioenergetics and Biomembranes, 1998
Molecular cloning of calcium channel subunit genes has identified an unexpectedly large number of genes and splicing variants, and a central problem of calcium channel biology is to now understand the functional significance of this genetic complexity. While electrophyisological, pharmacological, and molecular cloning techniques are providing one level

Voltage-Dependent Calcium Channels in Plant Vacuoles

Science, 1992
Free calcium (Ca 2+ ) in the cytoplasm of plant cells is important for the regulation of many cellular processes and the transduction of stimuli. Control of cytoplasmic Ca 2+ involves the activity of pumps, carriers, and possibly ion channels. The patch-clamp technique was used to study Ca

Toxins that affect voltage-dependent calcium channels

Biochemical Pharmacology, 1987
At this time, there are five potential candidates for calcium channel specific toxins. All five of these toxins appear to affect the function of voltage-dependent calcium channels. Atrotoxin, beta-leptinotarsin-h and maitotoxin activate channels, whereas both taicatoxin and omega-conotoxin are inhibitors.

In Vivo Analysis of Voltage-Dependent Calcium Channels

Journal of Bioenergetics and Biomembranes, 2003
The molecular cloning of calcium channel subunits has identified an unexpectedly large number of genes and splicing variants, many of whichhave complex expression patterns: a central problem of calcium channel biology is to understand the functional significance of this genetic complexity.
