That is a hallmark feature of hERG again. In Fig. The voltage dependence of channel activation . The total results indicate that the rate of activation of hERG and the chimaera is voltage dependent; the activation curves could be referred to with slow and fast activation time constants. 3b,c). These results indicate that the cytosolic domains of hERG are likely involved in the sluggish activation of hERG. Interestingly, such faster kinetics were defined for erg1-sm, a smooth muscles isoform of hERG, which lacks the C-terminal 101 proteins, but is otherwise nearly the same as the cardiac isoform. In this respect, again, the chimaera is comparable to erg1-sm which demonstrated large transient currents. Such large transients are also a characteristic feature of ELK stations, which are linked to hERG closely.Friedman, M.D., N.A.
