| molecular function |
|---|
| | GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| | GO:0086080 | | protein binding involved in heterotypic cell-cell adhesion | | Interacting selectively and non-covalently with any protein or protein complex contributing to the adhesion of two different types of cells. |
| | GO:0019904 | | protein domain specific binding | | Interacting selectively and non-covalently with a specific domain of a protein. |
| biological process |
|---|
| | GO:0007411 | | axon guidance | | The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues. |
| | GO:0007155 | | cell adhesion | | The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules. |
| | GO:0045162 | | clustering of voltage-gated sodium channels | | The process in which voltage-gated sodium channels become localized together in high densities. In animals, nodes of Ranvier differ dramatically from internodal axonal regions in very high densities of voltage-dependent sodium (Nav) channels responsible for the rapid, inward ionic currents that produce membrane depolarization. |
| | GO:0034113 | | heterotypic cell-cell adhesion | | The attachment of a cell to a cell of a different type via adhesion molecules. |
| | GO:0042552 | | myelination | | The process in which myelin sheaths are formed and maintained around neurons. Oligodendrocytes in the brain and spinal cord and Schwann cells in the peripheral nervous system wrap axons with compact layers of their plasma membrane. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier. |
| | GO:0030913 | | paranodal junction assembly | | Formation of the junction between an axon and the glial cell that forms the myelin sheath. Paranodal junctions form at each paranode, i.e. at the ends of the unmyelinated nodes of Ranvier. |
| | GO:0007422 | | peripheral nervous system development | | The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands. |
| | GO:0071205 | | protein localization to juxtaparanode region of axon | | Any process in which a protein is transported to, or maintained at, the juxtaparanode region of an axon. |
| | GO:0002175 | | protein localization to paranode region of axon | | A cellular protein localization process in which a protein is transported to, or maintained at, the paranode region of an axon. |
| | GO:0072661 | | protein targeting to plasma membrane | | The process of directing proteins towards the plasma membrane; usually uses signals contained within the protein. |
| | GO:0050808 | | synapse organization | | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a synapse, the junction between a neuron and a target (neuron, muscle, or secretory cell). |
| | GO:0019226 | | transmission of nerve impulse | | The neurological system process in which a signal is transmitted through the nervous system by a combination of action potential propagation and synaptic transmission. |
| cellular component |
|---|
| | GO:0097454 | | Schwann cell microvillus | | Small finger-like extension of a Schwann cell that contacts the nodal membrane. |
| | GO:0030424 | | axon | | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |
| | GO:0043194 | | axon initial segment | | Portion of the axon proximal to the neuronal cell body, at the level of the axon hillock. The action potentials that propagate along the axon are generated at the level of this initial segment. |
| | GO:0070062 | | extracellular exosome | | A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm. |
| | GO:0005925 | | focal adhesion | | Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments. |
| | GO:0016021 | | integral component of membrane | | 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. |
| | GO:0005622 | | intracellular | | The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. |
| | GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| | GO:0043209 | | myelin sheath | | An electrically insulating fatty layer that surrounds the axons of many neurons. It is an outgrowth of glial cells: Schwann cells supply the myelin for peripheral neurons while oligodendrocytes supply it to those of the central nervous system. |
| | GO:0033268 | | node of Ranvier | | An axon part that is a gap in the myelin where voltage-gated sodium channels cluster and saltatory conduction is executed. |
| | GO:0033010 | | paranodal junction | | A highly specialized cell-cell junction found in vertebrates, which forms between a neuron and a glial cell, and has structural similarity to Drosophila septate junctions. It flanks the node of Ranvier in myelinated nerve and electrically isolates the myelinated from unmyelinated nerve segments and physically separates the voltage-gated sodium channels at the node from the cluster of potassium channels underneath the myelin sheath. |
| | GO:0033270 | | paranode region of axon | | An axon part that is located adjacent to the nodes of Ranvier and surrounded by lateral loop portions of myelin sheath. |
| | GO:0005886 | | plasma membrane | | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
