Components
  • voltage-gated calcium channel complex
  • plasma membrane
  • endocytic vesicle membrane
  • AMPA glutamate receptor complex
General FunctionVoltage-gated calcium channel activity
Specific FunctionRegulates the trafficking and gating properties of AMPA-selective glutamate receptors (AMPARs). Promotes their targeting to the cell membrane and synapses and modulates their gating properties by slowing their rates of activation, deactivation and desensitization. Does not show subunit-specific AMPA receptor regulation and regulates all AMPAR subunits. Thought to stabilize the calcium channel in an inactivated (closed) state (By similarity).
