NMR Structure(hide GO term definitions)
Chain A   (MYC2_CRODU | Q9PWF3)
biological process
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
    GO:0050832    defense response to fungus    Reactions triggered in response to the presence of a fungus that act to protect the cell or organism.
    GO:0044564    envenomation resulting in occlusion of the pore of voltage-gated potassium channel in other organism    A process that begins with venom being forced into an organism by the bite or sting of another organism, and ends with a resultant blocking of a voltage-gated potassium channel, inhibiting the pore's activity, in the bitten/stung organism.
    GO:0031640    killing of cells of other organism    Any process in an organism that results in the killing of cells of another organism, including in some cases the death of the other organism. Killing here refers to the induction of death in one cell by another cell, not cell-autonomous death due to internal or other environmental conditions.
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.
