NMR Structure(hide GO term definitions)
Chain A   (TERT_APIME | P56587)
molecular function
    GO:0005516    calmodulin binding    Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.
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.
