Yongfeng Liu, Xianjin Xu, Junyuan Gao et al. perform in silico screening targeting compounds that resemble both KCNQ1 and PIP2 structures and identify CP1 as a compound that could restore KCNQ1 currents after PIP2 depletion. Like PIP2, this compound can mediate VSD-pore coupling of the channel, albeit via a different mechanism from PIP2.
