Calcium Channel Protein Type L Subunit Alpha 1C (CaV1.2)

Target
CaV1.2
Molecular classification
Ion channel, Voltage-dependent calcium channel, L-type calcium channel
01

Overview

The calcium channel protein type L subunit alpha 1C, commonly referred to as CaV1.2 or encoded by the gene CACNA1C, is the pore-forming alpha-1 subunit of the voltage-dependent L-type calcium channel. This protein mediates the influx of calcium ions into cells upon membrane depolarization and plays a critical role in various physiological processes, especially in excitable tissues such as cardiac and smooth muscle, neurons, pancreatic cells, and fibroblasts.
