Voltage-dependent L-type calcium channel subunit alpha-1C or Cav1.2 calcium channel (other names include as CACNA1C, CACH2, CACN2, CACNL1A1, CCHL1A1 ) is a calcium channel encoded by the gene CACNA1C. It is a member of the L type voltage dependent calcium channel family. These calcium channels mediate the influx of calcium ions into a cell upon membrane polarization. Cav1.2 is expressed in many tissues including smooth muscle, liver, kidney brain and heart. In brain, it can be detected in the hippocampus and brain cortex in the post-synaptic density and in neuronal cell bodies. Calcium channels are involved in many cell processes including muscle contraction, neurotransmitter release, gene expression, cell division and cell death. Mutations in the Cav1.2 gene have been associated with Timothy syndrome, Brugada syndrome 3 and Long QT syndrome 8.
