|
cellular_component
|
A location, relative to cellular compartments and structures, occupied by a macromolecular machine. There are three types of cellular components described in the gene ontology: (1) the cellular anatomical entity where a gene product carries out a molecular function (e.g., plasma membrane, cytoskeleton) or membrane-enclosed compartments (e.g., mitochondrion); (2) virion components, where viral proteins act, and (3) the stable macromolecular complexes of which gene product are parts (e.g., the clathrin complex). |

|
cellular anatomical structure
|
A part of a cellular organism consisting of a material entity with granularity above the level of a protein complex but below that of an anatomical system. Note that cellular organisms exclude viruses. |

GO:0030427
|
site of polarized growth
|
Any part of a cell where non-isotropic growth takes place. |
|
GO:0120025
|
plasma membrane bounded cell projection
|
A prolongation or process extending from a cell and that is bounded by plasma membrane, e.g. a cilium, lamellipodium, or axon. |
|
GO:0042995
|
cell projection
|
A prolongation or process extending from a cell, e.g. a flagellum or axon. |
|
GO:0043005
|
neuron projection
|
A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
|
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:0030426
|
growth cone
|
The migrating motile tip of a growing neuron projection, where actin accumulates, and the actin cytoskeleton is the most dynamic. |
|
GO:0150034
|
distal axon
|
That part of an axon close to and including the growth cone or the axon terminus. |
|
GO:0044295
|
axonal growth cone
|
The migrating motile tip of a growing nerve cell axon. |
