Target intelligence / Profile preview

Calcium Channel Protein (Vascular Smooth Muscle) (VSM Ca Channel)

Target
VSM Ca Channel
Molecular classification
Ion channel, Voltage-gated calcium channel
01

Overview

Calcium channel proteins in vascular smooth muscle (VSM) are integral membrane proteins that mediate the influx of calcium ions (Ca^{2+}) into smooth muscle cells. This calcium entry is essential for initiating and maintaining contraction, regulating vascular tone, and ultimately influencing systemic blood pressure. The most prominent type in VSM is the L-type voltage-gated calcium channel, specifically the CaV1.2 subtype.
