Calcium channel, voltage-dependent, T type, alpha 1G subunit, also known as CACNA1G or Ca_v3.1 is a protein which in humans is encoded by the CACNA1G gene.^[5]^[6]^[7] It is one of the primary targets in the pharmacology of absence seizure.

Function[]

Ca_v3.1 is a type of low-voltage-activated calcium channel, also known as "T-type" for its transient on and off.^[5] It is expressed in thalamocortical relay nucleus, and is responsible for the slow-wave sleep and absence seizure.^[8] During a slow-wave sleep, Ca_v3.1 is put into burst mode, and a self-sustaining synchronous cycle between cortex and thalamus is formed, sensory inputs are isolated from cortex; while awake the thalamus should instead relay sensory inputs from outside the central nervous system. The mechanism of absence seizure has a lot in common with slow-wave sleep. Therefore, a blocker that inhibits the burst mode activation of Ca_v3.1 is effective in treating absence seizures. Common drugs including ethosuximide, as well as trimethadione.^[8]
