Rabbit anti Rat Potassium ChannelCatalog number: X1038
Pore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels. May contribute to Icurrent in heart and current in neurons. Channel properties are modulated by interactions with other alpha subunits and with regulatory subunits In response to membrane depolarization, Kv4.2 channels accumulate in the closed-inactivated state(s), from which they directly recover, bypassing the open state. Kv4.2 is a substrate for ERK in vitro and in vivo, and suggest that ERK may regulate potassium-channel function by direct phosphorylation of the pore-forming alpha subunit.
Synonyms: RK5, Shal1, Kcnd2, Potassium voltage-gated channel subfamily D member 2
