Target intelligence / Profile preview

Calcium channel protein subunit alpha1C (CACNA1C)

Target
CACNA1C
Molecular classification
Ion channel, Voltage-gated calcium channel, L-type calcium channel
01

Overview

The CACNA1C gene encodes the alpha-1C subunit of a voltage-dependent L-type calcium channel (CaV1.2). This protein is crucial for mediating calcium influx into cells upon membrane depolarization, essential for cardiac action potentials, neurotransmission, gene expression, and other physiological processes. Mutations or dysregulation are linked to cardiac arrhythmias, neurodevelopmental disorders, and psychiatric conditions.
