"For instance, while we can reason that G375R (Liang et al., 2019; Figure 3A) may disrupt the opening of the activation gate since this is part of the diglycine hinge for the BK channel activation gate (Magidovich and Yifrach, 2004) and G356R may destroy the selectivity filter (Tao and MacKinnon, 2019; Figure 3A), we have no clue how the mutations in the cytosolic domain, such as N1053S (Zhang et al., 2015), N536H (Zhang et al., 2020), C413Y, or I663V (Liang et al., 2019; Figure 3A) may affect voltage dependent activation or the intrinsic gate opening in BK channels."

"The BK channel activation gate can open in the absence of voltage sensor activation and Ca 2+ binding with an intrinsic open probability of ~ 10 -7."
