EOG8NGK1Z GO:0016021 11/15 integral component of membrane cellular_component "The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane." [GOC:dos, GOC:go_curators] EOG8NGK1Z GO:0030054 7/15 cell junction cellular_component "A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix."

[GOC:mah, PMID:2466967] EOG8NGK1Z GO:0045211 7/15 postsynaptic membrane cellular_component "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 cross the synaptic cleft and transmit the signal to the postsynaptic membrane."
