RT subunit family enhances expression and speeds activation.";
RL Circ. Res. 88:E84-E87(2001).
CC -!- FUNCTION: Ancillary protein that assembles as a beta subunit with
CC a voltage-gated potassium channel complex of pore-forming alpha
CC subunits. Modulates the gating kinetics and enhances stability of
CC the channel complex. Associated with KCNH2/HERG is proposed to
CC form the rapidly activating component of the delayed rectifying
CC potassium current in heart (IKr). May associate with KCNQ2 and/or
CC KCNQ3 and modulate the native M-type current. May associate with
CC KCNQ1/KCLQT1 and elicit a voltage-independent current (By
CC similarity).
CC -!- SUBUNIT: Associates with KCNH2/ERG1 (By similarity). May associate
CC with KCNQ1/KVLQT1, KCNQ2 and KCNQ3. Associates with HCN1 and
CC probably HCN2 (By similarity).
CC -!- SUBCELLULAR LOCATION: Type I membrane protein.
CC -!- TISSUE SPECIFICITY: Detected in heart; expression is highest in
CC the SA node and the right atrium, and barely detectable in the
CC ventricle.
CC -!- SIMILARITY: Belongs to the potassium channel KCNE family.
