|
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). |

GO:0110165
|
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:0071944
|
cell periphery
|
The broad region around and including the plasma membrane of a cell, encompassing the cell cortex (inside the cell), the plasma membrane, and any external encapsulating structures. |
|
GO:0016020
|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. |
|
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. |
|
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:0098590
|
plasma membrane region
|
A membrane that is a (regional) part of the plasma membrane. |
|
GO:0031252
|
cell leading edge
|
The area of a motile cell closest to the direction of movement. |
|
GO:0043005
|
neuron projection
|
A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
|
GO:0031253
|
cell projection membrane
|
The portion of the plasma membrane surrounding a plasma membrane bounded cell surface projection. |
|
GO:0030425
|
dendrite
|
A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
|
GO:0097447
|
dendritic tree
|
The entire complement of dendrites for a neuron, consisting of each primary dendrite and all its branches. |
|
GO:0036477
|
somatodendritic compartment
|
The region of a neuron that includes the cell body (cell soma) and dendrite(s), but excludes the axon. |
|
GO:0032589
|
neuron projection membrane
|
The portion of the plasma membrane surrounding a neuron projection. |
|
GO:0031256
|
leading edge membrane
|
The portion of the plasma membrane surrounding the leading edge of a motile cell. |
|
GO:0032590
|
dendrite membrane
|
The portion of the plasma membrane surrounding a dendrite. |
