|
cytoplasm
|
The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
|
GO:0005575
|
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:0005622
|
intracellular anatomical structure
|
A component of a cell contained within (but not including) the plasma membrane. In eukaryotes it includes the nucleus and cytoplasm. |
|
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:0043227
|
membrane-bounded organelle
|
Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
|
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:0043229
|
intracellular organelle
|
Organized structure of distinctive morphology and function, occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton. Excludes the plasma membrane. |
|
GO:0043231
|
intracellular membrane-bounded organelle
|
Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
|
GO:0012505
|
endomembrane system
|
A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. |
|
GO:0031984
|
organelle subcompartment
|
A compartment that consists of a lumen and an enclosing membrane, and is part of an organelle. |
|
GO:0031985
|
Golgi cisterna
|
Any of the thin, flattened membrane-bounded compartments that form the central portion of the Golgi complex. |
|
GO:0016020
|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. |
|
GO:0031090
|
organelle membrane
|
A membrane that is one of the two lipid bilayers of an organelle envelope or the outermost membrane of single membrane bound organelle. |
|
GO:0005795
|
Golgi stack
|
The set of thin, flattened membrane-bounded compartments, called cisternae, that form the central portion of the Golgi complex. The stack usually comprises cis, medial, and trans cisternae; the cis- and trans-Golgi networks are not considered part of the stack. |
|
GO:0005794
|
Golgi apparatus
|
A membrane-bound cytoplasmic organelle of the endomembrane system that further processes the core oligosaccharides (e.g. N-glycans) added to proteins in the endoplasmic reticulum and packages them into membrane-bound vesicles. The Golgi apparatus operates at the intersection of the secretory, lysosomal, and endocytic pathways. |
|
GO:0098791
|
Golgi apparatus subcompartment
|
A compartment that consists of a lumen and an enclosing membrane, and is part of the Golgi apparatus. |
|
GO:0032580
|
Golgi cisterna membrane
|
The lipid bilayer surrounding any of the thin, flattened compartments that form the central portion of the Golgi complex. |
