|
cellular process
|
Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. |
|
GO:0051179
|
localization
|
Any process in which a cell, a substance, or a cellular entity, such as a protein complex or organelle, is transported, tethered to or otherwise maintained in a specific location. In the case of substances, localization may also be achieved via selective degradation. |
|
GO:0008150
|
biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |
|
GO:0022857
|
transmembrane transporter activity
|
Enables the transfer of a substance, usually a specific substance or a group of related substances, from one side of a membrane to the other. |
|
GO:0005215
|
transporter activity
|
Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, accross or in between cells. |
|
GO:0003674
|
molecular_function
|
A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs. |
|
GO:0051234
|
establishment of localization
|
Any process that localizes a substance or cellular component. This may occur via movement, tethering or selective degradation. |
|
GO:0006810
|
transport
|
The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter or a transporter complex, a pore or a motor protein. |
|
GO:0055085
|
transmembrane transport
|
The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. |
|
GO:0022829
|
wide pore channel activity
|
Enables the energy-independent facilitated diffusion of propanediol through a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts. |
|
GO:0015267
|
channel activity
|
Enables the energy-independent facilitated diffusion of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. |
|
GO:0022803
|
passive transmembrane transporter activity
|
Enables the transfer of a single solute from one side of a membrane to the other by a mechanism involving conformational change, either by facilitated diffusion or in a membrane potential dependent process if the solute is charged. |
|
GO:0005243
|
gap junction channel activity
|
A wide pore channel activity that enables a direct cytoplasmic connection from one cell to an adjacent cell. The gap junction can pass large solutes as well as electrical signals between cells. Gap junctions consist of two gap junction hemi-channels, or connexons, one contributed by each membrane through which the gap junction passes. |
|
GO:0055077
|
gap junction hemi-channel activity
|
A wide pore channel activity that enables the transport of a solute across a membrane via a gap junction hemi-channel. Two gap junction hemi-channels coupled together form a complete gap junction. |
