Protein Structure
UniProt Annotation
Function Ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Modulates the gating kinetics and enhances stability of the channel complex. Associated with KCNH2/HERG is proposed to form the rapidly activating component of the delayed rectifying potassium current in heart (IKr). May associate with KCNQ2 and/or KCNQ3 and modulate the native M-type current. May associate with KCNQ1/KCLQT1 and elicit a voltage-independent current (By similarity). {ECO:0000250}.
Subcellular Localization Membrane; Single-pass type I membrane protein.
