Voltage-dependent L-type calcium channel subunit alpha-1F
[Isoform 1]: Voltage-sensitive calcium channels (VSCC) mediate the entry of calcium ions into excitable cells and are also involved in a variety of calcium-dependent processes, including muscle contraction, hormone or neurotransmitter release, gene expression, cell motility, cell division and cell death. The isoform alpha-1F gives rise to L-type calcium currents. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group. They are blocked by dihydropyridines (DHP), phenylalkylamines, and by benzothiazepines. Activates at more negative voltages and does not undergo calcium-dependent inactivation (CDI), due to incoming calcium ions, during depolarization.; [Isoform 4]: Voltage-dependent L-type calcium channel activates at more hyperpolarized voltages and exhibits a robust calcium-dependent inactivation (CDI), due to incoming calcium ions, during depolarizations.; [Isoform 6]: Voltage-dependent L-type calcium channel activates at more hyperpolarized voltages and exhibits a robust calcium-dependent inactivation (CDI), due to incoming calcium ions, during depolarizations. {ECO:0000269|}.
