voltage-gated calcium channel complex

Definition

Target type: cellularcomponent

A protein complex that forms a transmembrane channel through which calcium ions may pass in response to changes in membrane potential. [GOC:mah]

The voltage-gated calcium channel complex is a multi-protein assembly embedded in the plasma membrane of excitable cells, playing a crucial role in regulating calcium influx. This complex comprises several subunits, each with distinct functions:

**1. α1 subunit:**
- The pore-forming subunit, responsible for selective calcium permeability.
- Contains voltage-sensing domains (VSDs) that respond to changes in membrane potential, triggering channel opening.
- Exhibits diverse isoforms, contributing to the heterogeneity of calcium channels.

**2. β subunit:**
- Regulates trafficking and surface expression of the α1 subunit.
- Interacts with the α1 subunit's intracellular loop, influencing channel gating and inactivation.

**3. α2δ subunit:**
- Anchors the channel complex to the cell membrane through its interaction with extracellular matrix proteins.
- Modulates channel activity through its interaction with the α1 subunit.

**4. γ subunit:**
- Primarily associated with L-type calcium channels.
- Enhances channel function and regulates its interaction with other components.

**5. Auxiliary subunits:**
- Include proteins like calmodulin and interacting proteins, modulating channel activity.

**Cellular Location:**
- Primarily localized to the plasma membrane of excitable cells, including neurons, muscle cells, and endocrine cells.
- Specific subtypes may exhibit unique subcellular localization patterns.

**Functional Significance:**
- Regulates calcium influx, which triggers a cascade of downstream signaling events.
- Plays a critical role in various cellular processes, including neurotransmitter release, muscle contraction, hormone secretion, and gene expression.

**Regulation:**
- Voltage-dependent gating: Opens upon membrane depolarization, allowing calcium influx.
- Ligand-dependent modulation: Can be regulated by intracellular messengers like calcium and phosphorylation.
- Modulation by auxiliary subunits and interacting proteins: Fine-tunes channel activity.

The complex structure and diverse regulation mechanisms of the voltage-gated calcium channel complex allow it to play a pivotal role in maintaining cellular homeostasis and mediating various physiological processes.'
