Cav1.2 is a type of voltage-gated calcium channel that is predominantly found in cardiac and smooth muscle, as well as in neurons. It is a member of the Cav1 family of calcium channels and is also known as the alpha-1C subunit of the channel. These channels are critical for the influx of calcium ions (Ca²⁺) into cells, which is essential for various physiological processes, including muscle contraction, neurotransmitter release, and gene expression.
