NMR Structure(hide GO term definitions)
Chain A   (TOG4A_AGEAP | P30288)
molecular function
    GO:0019855    calcium channel inhibitor activity    Stops, prevents, or reduces the activity of a calcium channel.
    GO:0008200    ion channel inhibitor activity    Stops, prevents, or reduces the activity of an ion 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.
    GO:0072556    other organism presynaptic membrane    A presynaptic membrane that is part of another organism, i.e. a secondary organism with which the first organism is interacting. A presynaptic membrane is specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane.
