R-type calcium channel

R-type calcium channels are a specific type of voltage-gated calcium channel that is primarily involved in the modulation of synaptic transmission and the regulation of various physiological processes in excitatory neurons. These channels play a critical role in the influx of calcium ions (Ca²⁺) into cells in response to depolarization of the cell membrane. R-type calcium channels are classified based on their response to voltage and their pharmacological properties.
