|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
|
GO:0019898
|
extrinsic component of membrane
|
The component of a membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region. |
|
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: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: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:0005834
|
heterotrimeric G-protein complex
|
Any of a family of heterotrimeric GTP-binding and hydrolyzing proteins; they belong to a superfamily of GTPases that includes monomeric proteins such as EF-Tu and RAS. Heterotrimeric G-proteins consist of three subunits; the alpha subunit contains the guanine nucleotide binding site and possesses GTPase activity; the beta and gamma subunits are tightly associated and function as a beta-gamma heterodimer; extrinsic plasma membrane proteins (cytoplasmic face) that function as a complex to transduce signals from G-protein coupled receptors to an effector protein. |
|
GO:1902494
|
catalytic complex
|
A protein complex which is capable of catalytic activity. |
|
GO:0044464
|
cell part
|
Any constituent part of a cell, the basic structural and functional unit of all organisms. |
|
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: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:0071944
|
cell periphery
|
The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures. |
|
GO:0098796
|
membrane protein complex
|
Any protein complex that is part of a 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:0098797
|
plasma membrane protein complex
|
Any protein complex that is part of the plasma membrane. |
|
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:0031234
|
extrinsic component of cytoplasmic side of plasma membrane
|
The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region. |
|
GO:0009898
|
cytoplasmic side of plasma membrane
|
The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface. |
|
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:0019897
|
extrinsic component of plasma membrane
|
The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to one of its surfaces, but not integrated into the hydrophobic region. |
