NMR Structure(hide GO term definitions)
Chain A   (CM3A_CONSE | P60207)
molecular function
    GO:0019871    sodium channel inhibitor activity    Stops, prevents, or reduces the activity of a sodium channel.
biological process
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
