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 kinetics\cite{9495342, 10066244, 2419479}. For characterizing the deactivation kinetics of DmCav3, DmCa\textsubscript{v}3,  we transiently expressed DmCav3 DmCa\textsubscript{v}3  cDNA in HEK-293 cells and recorded tail currents using whole cell patch clamping. The tail currents of DmCav3 DmCa\textsubscript{v}3  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 Ca\textsubscript{v}3.3  among the three Cav3 Ca\textsubscript{v}3  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.
