Voltage-dependent calcium channel subunit alpha-2/delta

IPR051173

Definition

The calcium channel subunit alpha-2/delta family comprises proteins that act as regulatory subunits for voltage-dependent calcium channels, influencing calcium current density and activation/inactivation kinetics. These subunits are involved in various calcium-dependent processes, including excitation-contraction coupling and neural depolarization-induced calcium influx. They contain a MIDAS-like motif within the VWFA domain that binds divalent metal cations, essential for trafficking the alpha-1 subunit to the plasma membrane. Some family members may also regulate calcium-activated signaling pathways affecting motor activity and neurotransmitter responses.
