Fig. 4From: Immunosuppressive effects of a novel potassium channel toxin Ktx-Sp2 from Scorpiops PocokiKtx-Sp2 inhibit Kv1.3 endogenously expressed by Jurkat T cells. a Representative traces illustrate that Ktx-Sp2 inhibited the Kv1.3 current in a Jurkat T cell in a concentration-dependent manner. b Concentration–response curve of Ktx-Sp2 inhibition of Kv1.3 current in Jurkat T cells. Currents were normalized to the control and fitted by a Hill equationBack to article page
