Definition: In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.
Input: Severe Acute Respiratory Syndrome (SARS) is caused by a novel coronavirus (SARS-CoV). Coronaviruses including SARS-CoV encode an envelope (E) protein, a small, hydrophobic membrane protein. We report that, in planar lipid bilayers, synthetic peptides corresponding to the SARS-CoV E protein forms ion channels that are more permeable to monovalent cations than to monovalent anions. Affinity-purified polyclonal antibodies recognizing the N-terminal 19 residues of SARS-CoV E protein were used to establish the specificity of channel formation by inhibiting the ion currents generated in the presence of the E protein peptides.
