At the test potentials from \textminus50 mV to +20 mV, DmCa\textsubscript{v}3 has slower current kinetics than Ca\textsubscript{v}3.1 (P $<$ 0.01 or 0.001, Fig. 1c).  For example, the activation and inactivation time constants of DmCa\textsubscript{v}3 current at \textminus20 mV test potential are 2.2 $\pm$ 0.2 ms and 23.4 $\pm$ 1.4 ms respectively, showing about 2-fold slower activation and inactivation kinetics than those of rat Ca\textsubscript{v}3.1 current (Table 1).  One of defining properties of T-type calcium channels is that they deactivate slowly compared to the HVA calcium channels that have much faster deactivation kinetics1,4,6. kinetics\cite{9495342, 10066244, 2419479}.  For characterizing the deactivation kinetics of DmCav3, we transiently expressed DmCav3 cDNA in HEK-293 cells and recorded tail currents using whole cell patch clamping. The tail currents of DmCav3 appeared to be slowly decayed in a voltage dependent manner (Fig. 1d). The deactivation time constants from fitting the tail currents are most similar to mammalian Cav3.3 among the three Cav3 isoforms previously reported (Table 1). Previous studies have shown that the current amplitude of Ca\textsubscript{v}3.1 in Ca\textsubscript{v}3 as a charge carrier is greater than in equi-molar Ba\textsuperscript{2+}, while the opposite is true for Ca\textsubscript{v}3.2 or Ca\textsubscript{v}3.3\cite{mcrory:2000aa,shcheglovitov:2007aa}.  Herein, we determined relative permeability (ICa/IBa) of Ca\textsubscript{v}3 and Ba\textsuperscript{2+} ions through DmCa\textsubscript{v}3 or Ca\textsubscript{v}3.1.
