DT Family Voltage-Gated Ion Channel (VIC) Superfamily ;
Tissue Specificity Highly expressed in heart and brain. IsoformsUSO are frequently overexpressed in cancer cells.
Function This transporter mediates the rapidly activating component of the delayed rectifying potassium current in heart (IKr). Pore-forming (alpha) subunit of voltage-gated inwardly rectifying potassium channel. Channel properties are modulated by cAMP and subunit assembly.
Endogenous Substrate(s) Potassium ions
