NMR Structure(hide GO term definitions)
Chain A   (CA1A_CONGE | P01519)
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:0035792    other organism postsynaptic membrane    A postsynaptic membrane that is part of another organism, i.e. a secondary organism with which the first organism is interacting. A postsynaptic membrane is a specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters transmit the signal across the synaptic cleft to the postsynaptic membrane.
