|
catalytic complex
|
A protein complex which is capable of catalytic activity. |
|
GO:0032991
|
protein-containing complex
|
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. |
|
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: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:0098796
|
membrane protein complex
|
Any protein complex that is part of a membrane. |
|
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:0098797
|
plasma membrane protein complex
|
Any protein complex that is part of the plasma membrane. |
|
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: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: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:1905360
|
GTPase complex
|
A protein complex which is capable of GTPase activity. |
|
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. |
