Structure and Regulation of Voltage-Gated Ca 2+ Channels

Catterall, William A.·2000·Annual Review of Cell and Developmental Biology

Abstract

▪ Abstract Voltage-gated Ca 2+ channels mediate Ca 2+ entry into cells in response to membrane depolarization. Electrophysiological studies reveal different Ca 2+ currents designated L-, N-, P-, Q-, R-, and T-type. The high-voltage-activated Ca 2+ channels that have been characterized biochemically are complexes of a pore-forming α 1 subunit of ∼190–250 kDa; a transmembrane, disulfide-linked complex of α 2 and δ subunits; an intracellular β subunit; and in some cases a transmembrane γ subunit. Ten α 1 subunits, four α 2 δ complexes, four β subunits, and two γ subunits are known. The Ca v 1 family of α 1 subunits conduct L-type Ca 2+ currents, which initiate muscle contraction, endocrine secretion, and gene transcription, and are regulated primarily by second messenger-activated protein phosphorylation pathways. The Ca v 2 family of α 1 subunits conduct N-type, P/Q-type, and R-type Ca 2+ currents, which initiate rapid synaptic transmission and are regulated primarily by direct interaction with G proteins and SNARE proteins and secondarily by protein phosphorylation. The Ca v 3 family of α 1 subunits conduct T-type Ca 2+ currents, which are activated and inactivated more rapidly and at more negative membrane potentials than other Ca 2+ current types. The distinct structures and patterns of regulation of these three families of Ca 2+ channels provide a flexible array of Ca 2+ entry pathways in response to changes in membrane potential and a range of possibilities for regulation of Ca 2+ entry by second messenger pathways and interacting proteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
