T-type voltage-gated calcium channel 3.2 (Cav3.2)

Target
Cav3.2
Molecular classification
Voltage-gated calcium channel, CaV3 subfamily, Ion channel
01

Overview

Cav3.2 is a subtype of T-type voltage-gated calcium channels, encoded by the CACNA1H gene. It is widely expressed throughout the central nervous system and peripheral tissues, playing critical roles in neuronal excitability, pacemaking activity, and pain signaling. Dysfunction or altered expression/activity of Cav3.2 has been linked to several disorders, including neuropathic pain and absence epilepsy, making it a promising target for analgesics development.
