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:0036477
|
somatodendritic compartment
|
The region of a neuron that includes the cell body (cell soma) and dendrite(s), but excludes the axon. |
GO:0043025
|
neuronal cell body
|
The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
GO:0032809
|
neuronal cell body membrane
|
The plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites. |
GO:0044298
|
cell body membrane
|
The plasma membrane of a cell that bears surface projections such as axons, dendrites, cilia, or flagella, excluding the plasma membrane on cell projections. |
GO:0044297
|
cell body
|
The portion of a cell bearing surface projections such as axons, dendrites, cilia, or flagella that includes the nucleus, but excludes all cell projections. |
