Calcium channel, voltage-dependent, T type, alpha 1I subunit,also known asCACNA1IorCa_v3.3is aproteinwhich in humans is encoded by theCACNA1Igene.^[5]^[6]^[7]

Function

Voltage-dependent calcium channelscan be distinguished based on their voltage-dependence, deactivation, and single-channel conductance. Low-voltage-activated calcium channels are referred to as 'T' type because their currents are both transient, owing to fast inactivation, and tiny, owing to small conductance. T-type channels are thought to be involved in pacemaker activity, low-threshold calcium spikes, neuronal oscillations and resonance, and rebound burst firing.^[5]
