Dengue virus M protein C-terminal peptide (DVM-C) forms ion channels

Premkumar, Anita; Horan, Catherine; Gage, Peter


A chemically synthesized peptide consisting of the C-terminus of the M protein of the Dengue virus type 1 strain Singapore S275/90 (DVM-C) produced ion channel activity in artificial lipid bilayers. The channels had a variable conductance and were more permeable to sodium and potassium ions than to chloride ions and more permeable to chloride ions than to calcium ions. Hexamethylene amiloride (100 μM) and amantadine (10 μM), blocked channels formed by DVM-C. Ion channels may play an important...[Show more]
