model.
Properties of 
are derived from experimental data of Okabe et al., [49] in rat circular myometrial cells and adjusted to experimental data of longitudinal cells [48]. A, V-dependent activation steady-state (
); B, V-dependent activation time constant (
). C, simulated voltage-clamp 
at voltage steps of 
to 
from a holding potential of 
. D, simulated I–V relationship of 
and experimental I–V data Satoh [48]. In both C and D, all data are normalized to the current value at
