CACNA1C (Cav1.2) and psychiatric disease

The calcium channel, voltage-dependent, L type, alpha 1C subunit is a protein that is encoded by the CACNA1C gene. Via calcium channels calcium influxes into cells. Mutations in CACNA1C are associated with bipolar disorder, depression, schizophrenia and autism. Gain of function mutations in CACNA1C are associated with disease, for example, autism.

Taurine regulates intracellular calcium levels by preventing influxes of calcium into cells but not effluxes of calcium out of cells. Via regulating influxes of calcium into cells taurine has a role in the treatment of psychiatric disorders that are in part due to gain of function mutations in CACNA1C.
