| Identifier | Name | Description |
|---|---|---|
| GO:0016020 | membrane | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| GO:0005737 | cytoplasm | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005622 | intracellular | The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. |
| GO:0005789 | endoplasmic reticulum membrane | The lipid bilayer surrounding the endoplasmic reticulum. |
| 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:0005783 | endoplasmic reticulum | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| GO:0044464 | cell part | Any constituent part of a cell, the basic structural and functional unit of all organisms. |
| GO:0044444 | cytoplasmic part | Any constituent part of the cytoplasm, all of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0044424 | intracellular part | Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. |
| 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: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:0044422 | organelle part | Any constituent part of an organelle, an organized structure of distinctive morphology and function. Includes constituent parts of the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton, but excludes the plasma membrane. |
| GO:0044446 | intracellular organelle part | A constituent part of an intracellular organelle, an organized structure of distinctive morphology and function, occurring within the cell. Includes constituent parts of the nucleus, mitochondria, plastids, vacuoles, vesicles, ribosomes and the cytoskeleton but excludes the plasma membrane. |
| GO:0098588 | bounding membrane of organelle | The lipid bilayer that forms the outer-most layer of an organelle. |
| 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: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: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:0044432 | endoplasmic reticulum part | Any constituent part of the endoplasmic reticulum, the irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. |
| GO:0042175 | nuclear outer membrane-endoplasmic reticulum membrane network | The continuous network of membranes encompassing the nuclear outer membrane and the endoplasmic reticulum membrane. |
| GO:0005790 | smooth endoplasmic reticulum | The smooth endoplasmic reticulum (smooth ER or SER) has no ribosomes attached to it. The smooth ER is the recipient of the proteins synthesized in the rough ER. Those proteins to be exported are passed to the Golgi complex, the resident proteins are returned to the rough ER and the lysosomal proteins after phosphorylation of their mannose residues are passed to the lysosomes. Glycosylation of the glycoproteins also continues. The smooth ER is the site of synthesis of lipids, including the phospholipids. The membranes of the smooth ER also contain enzymes that catalyze a series of reactions to detoxify both lipid-soluble drugs and harmful products of metabolism. Large quantities of certain compounds such as phenobarbital cause an increase in the amount of the smooth ER. |
| GO:0098562 | cytoplasmic side of membrane | The side of a membrane that faces the cytoplasm. |
| GO:0098552 | side of membrane | A cellular component consisting of one leaflet of a membrane bilayer and any proteins embedded or anchored in it or attached to its surface. |
| GO:0097478 | leaflet of membrane bilayer | Any of the two layers of lipid molecules that constitute a membrane. |
| GO:0097425 | smooth endoplasmic reticulum part | Any constituent part of the smooth endoplasmic reticulum (also called smooth ER, or SER). |
| GO:0030868 | smooth endoplasmic reticulum membrane | The lipid bilayer surrounding the smooth endoplasmic reticulum. |
| GO:0098554 | cytoplasmic side of endoplasmic reticulum membrane | The side (leaflet) of the plasma membrane that faces the cytoplasm. |
| GO:0098557 | cytoplasmic side of smooth endoplasmic reticulum membrane | The side (leaflet) of the smooth endoplasmic reticulum membrane that faces the cytoplasm. |
