p-KCND2/Kv4.2(Thr607), p-Kv4.2(Thr607), Potassium voltage-gated channel subfamily D member 2, KCD2, KCND 2, KCND2, KCND2_HUMAN, KIAA1044, Potassium voltage gated channel Shal related subfamily member 2, RK 5, RK5, Voltage gated potassium channel Kv4.2, Voltage gated potassium channel subunit Kv4.2, Voltage sensitive potassium channel, voltage-gated potassium channel Kv4.2, Voltage-gated potassium channel subunit Kv4.2, voltage-sensitive potassium channel.
Voltage-gated K+ channels in the plasma membrane control the repolarization and the frequency of action potentials in neurons, muscles, and other excitable cells. Pore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels. May contribute to I(To) current in heart and I(Sa) current in neurons. Channel properties are modulated by interactions with other alpha subunits and with regulatory subunits.
