Function

Functions as a voltage-gated inward-rectifying Ca(2+) channel (VDCC) across the plasma membrane that mediates sucrose-induced Ca(2+) influx in autotrophically grown leaf cells. Acts as the major ROS-responsive Ca(2+) channel and is the possible target of Al-dependent inhibition. Plays a regulatory role in defense responses.
