NMR Structure(hide GO term definitions)
Chain A   (SCXA_MESMA | O61705)
molecular function
    GO:0008200    ion channel inhibitor activity    Stops, prevents, or reduces the activity of an ion channel.
    GO:0019870    potassium channel inhibitor activity    Stops, prevents, or reduces the activity of a potassium channel.
    GO:0019871    sodium channel inhibitor activity    Stops, prevents, or reduces the activity of a sodium channel.
biological process
    GO:0006952    defense response    Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
    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.
