Name Voltage-dependent calcium channel subunit alpha-2/delta-2
Synonyms
  1. Voltage-dependent calcium channel subunit alpha-2-2
  2. Voltage-dependent calcium channel subunit delta-2
  3. Voltage-gated calcium channel subunit alpha-2/delta-2
Gene Name CACNA2D2
Protein Type Unknown
Biological Properties
General Function Involved in calcium channel activity
Specific Function The alpha-2/delta subunit of voltage-dependent calcium channels regulates calcium current density and activation/inactivation kinetics of the calcium channel. Acts as a regulatory subunit for P/Q-type calcium channel (CACNA1A), N-type (CACNA1B), L-type (CACNA1C OR CACNA1D) and possibly T-type (CACNA1G). Overexpression induces apoptosis
