|
membrane
|
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
|
GO:0016021
|
integral component of membrane
|
The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
|
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:0005887
|
integral component of plasma membrane
|
The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
|
GO:0031224
|
intrinsic component of membrane
|
The component of a membrane consisting of the gene products having some covalently attached portion, for example part of a peptide sequence or some other covalently attached group such as a GPI anchor, which spans or is embedded in one or both leaflets of the membrane. |
|
GO:0001518
|
voltage-gated sodium channel complex
|
A sodium channel in a cell membrane whose opening is governed by the membrane potential. |
|
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:0031226
|
intrinsic component of plasma membrane
|
The component of the plasma membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane. |
|
GO:0034706
|
sodium channel complex
|
An ion channel complex through which sodium ions pass. |
|
GO:0034703
|
cation channel complex
|
An ion channel complex through which cations pass. |
|
GO:1990351
|
transporter complex
|
A protein complex facilitating transport of molecules (proteins, small molecules, nucleic acids) into, out of or within a cell, or between cells. |
|
GO:1902495
|
transmembrane transporter complex
|
A transmembrane protein complex which enables the transfer of a substance from one side of a membrane to the other. |
|
GO:0034702
|
ion channel complex
|
A protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective ion transport down its electrochemical gradient. |
