The number of ion channels expressed on the cell surface shapes the complex electrical response of excitable cells. Maintaining a balance between anterograde and retrograde trafficking of channel proteins is vital in regulating steady-state cell surface expression. Kv1.5 is an important voltage-gated K(+) channel in the cardiovascular system underlying the ultra-rapid rectifying potassium current (Ik(ur)), a major repolarizing current in atrial myocytes, and regulating the resting membrane… CONTINUE READING
