Protein: Voltage-dependent R-type calcium channel subunit alpha-1E (BII) (Brain calcium channel II) (Calcium channel, L type, alpha-1 polypeptide, isoform 6) (RBE-II) (RBE2) (Voltage-gated calcium channel subunit alpha Cav2.3) (Q07652)
Organism: Rattus norvegicus (Rat)
Function: 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-1E gives rise to R-type calcium currents. R-type calcium channels belong to the 'high-voltage activated' (HVA) group and are blocked by nickel. They are however insensitive to dihydropyridines (DHP). Calcium channels containing alpha-1E subunit could be involved in the modulation of firing patterns of neurons which is important for information processing.
Subcellular location: Membrane {ECO:0000255}; Multi-pass membrane protein {ECO:0000255}.
