reach
"KCNE1 complexes with KCNQ1 to both slow its voltage stimulated activation and to enhance its open state conductance, resulting in the I Ks current of the cardiac action potential."

reach
"KCNE1 regulates the potassium voltage-gated channel subfamily Q member 1 (KCNQ1) channel in a variety of ways : by slowing voltage-stimulated channel activation, increasing conductance, and eliminating channel inactivation."

reach
"C28 is another KCNQ1 activator molecule but binds to and stabilizes the voltage sensor domain, thereby decreasing the voltage required for voltage-dependent KCNQ1 activation (Lin et al., 2021)."

reach
"Phosphorylation of KCNQ1 decreases the voltage dependence for activation of the channel, increasing the rate of activation and decreasing the rate of deactivation."

reach
"The time- and voltage dependent current had biophysical properties typical of cardiac KCNQ1 and KCNE1 current and was almost completely abolished by KCNQ1 blocker chromanol 293B (50 microM)."
