GO:0001507,BP,"acetylcholine catabolic process in synaptic cleft","The chemical reactions and pathways resulting in the breakdown of acetylcholine that occurs in the synaptic cleft during synaptic transmission.",TAS
GO:0005581,CC,"collagen trimer","A protein complex consisting of three collagen chains assembled into a left-handed triple helix. These trimers typically assemble into higher order structures.",IEA
GO:0005605,CC,"basal lamina","A thin sheet of proteoglycans and glycoproteins, especially laminin, secreted by cells as an extracellular matrix.",IEA
GO:0005615,CC,"extracellular space","That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.",TAS
GO:0005886,CC,"plasma membrane","The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.",IEA
GO:0008105,BP,"asymmetric protein localization","Any process in which a protein is transported to, or maintained in, a specific location such that it is distributed asymmetrically.",TAS
GO:0008582,BP,"regulation of synaptic growth at neuromuscular junction","Any process that modulates the frequency, rate or extent of synaptic growth at neuromuscular junctions.",ISS
GO:0030054,CC,"cell junction","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.",IEA
GO:0031594,CC,"neuromuscular junction","The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential.",ISS
GO:0043083,CC,"synaptic cleft","The narrow gap that separates the presynaptic and postsynaptic membranes, into which neurotransmitter is released.",IEA
GO:0071340,BP,"skeletal muscle acetylcholine-gated channel clustering","The accumulation of acetylcholine-gated cation channels in a narrow, central region of muscle fibers, in apposition to nerve terminals.",ISS
GO:0090150,BP,"establishment of protein localization to membrane","The directed movement of a protein to a specific location in a membrane.",IDA
