Successful
Target Bioclass
Transporter and channel
Family
Potassium channel family, D (Shal) (TC 1.A.1.2) subfamily, Kv4.3/KCND3 sub-subfamily
Subcellular location
Cell membrane
Function
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.
