R-type Voltage-Gated Calcium Channel (Cav2.3)

Target
Cav2.3
Molecular classification
Ion channel, Voltage-gated calcium channel
01

Overview

The Cav2.3/R-type voltage-gated calcium channel plays an essential role in neuronal excitability and synaptic transmission within key brain regions. Its unique pharmacological profile makes it both an interesting research target for understanding neurophysiology as well as a promising candidate for therapeutic intervention—particularly concerning certain types of epilepsies where its modulation may have clinical benefit.
