GO:0016020
|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
GO:0043234
|
protein complex
|
A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical. |
GO:0031514
|
motile cilium
|
A cilium which has a variable arrangement of axonemal microtubules, contains molecular motors, and beats with a characteristic whip-like pattern that promotes cell motility or transport of fluids and other cells across a cell surface. Motile cilia are typically found in multiple copies on epithelial cells that line the lumenal ducts of various tissues. Motile cilia may also function as sensory organelles. |
GO:0044464
|
cell part
|
Any constituent part of a cell, the basic structural and functional unit of all organisms. |
GO:0032991
|
macromolecular complex
|
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which the constituent parts function together. |
GO:0005575
|
cellular_component
|
The part of a cell or its extracellular environment in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together. |
GO:0005623
|
cell
|
The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope. |
GO:0043226
|
organelle
|
Organized structure of distinctive morphology and function. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, and prokaryotic structures such as anammoxosomes and pirellulosomes. Excludes the plasma membrane. |
GO:0044425
|
membrane part
|
Any constituent part of a membrane, a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. |
GO:0044459
|
plasma membrane part
|
Any constituent part of the 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:0042995
|
cell projection
|
A prolongation or process extending from a cell, e.g. a flagellum or axon. |
GO:0005929
|
cilium
|
A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body. |
GO:0098589
|
membrane region
|
A membrane that is a part of a larger membrane. Examples include the apical region of the plasma membrane of an epithelial cell and the various regions of the endoplasmic reticulum membrane. |
GO:0098590
|
plasma membrane region
|
A membrane that is a (regional) part of the plasma membrane. |
GO:0030990
|
intraciliary transport particle
|
A nonmembrane-bound oligomeric protein complex that participates in bidirectional transport of molecules (cargo) along axonemal microtubules. |
