Calcium channels are composed of a specialized structure, a complex protein placed to bridge the intracellular and extracellular media across the lipidic cell membrane. Under the control of the difference of potential across the cell membrane (membrane voltage or Vm) and biochemical pathways, these ...

The α1A gene encodes the pore-forming subunit of a high-voltage-activated Ca2+ channel that is sensitive to ω-Aga IVA and ω-CTx MVIIC (Mori et al., 1991, Sather et al., 1993). The α1A subunit has also been shown to interact with the neuronal β subunits β1b, β2, β3,...

Plasma Membrane Expression of T-type Calcium Channel α1 Subunits Is Modulated by High Voltage-activated Auxiliary Subunits It has been suggested that the auxiliary subunits of high voltage-activated (HVA) calcium channels modulate T-type, low voltage-activated (LVA) calcium cha... SJ Dubel,C Al...
Prabhakar. Ca2+ current in rabbit carotid body glomus cells is conducted by multiple types of high-voltage–activated Ca2+ channels. J. Neurophysiol. 78: 2467–2474, 1997. Carotid bodies are sensory organs that detect changes in arterial oxygen. Glomus cells are presumed to be the initial ...
Calcium influx into cardiac myocytes via voltage-gated Ca channels is a key step in initiating the contractile response. During prolonged depolarizations, toxic Ca2+ overload is prevented by channel inactivation occurring through two different processes identified by their primary trigger: voltage or int...
