|
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: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:0042613
|
MHC class II protein complex
|
A transmembrane protein complex composed of an MHC class II alpha and MHC class II beta chain, and with or without a bound peptide or polysaccharide antigen. |
|
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: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:0042611
|
MHC protein complex
|
A transmembrane protein complex composed of an MHC alpha chain and, in most cases, either an MHC class II beta chain or an invariant beta2-microglobin chain, and with or without a bound peptide, lipid, or polysaccharide antigen. |
