|
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: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:0071840
|
cellular component organization or biogenesis
|
A process that results in the biosynthesis of constituent macromolecules, assembly, arrangement of constituent parts, or disassembly of a cellular component. |
|
GO:0016043
|
cellular component organization
|
A process that results in the assembly, arrangement of constituent parts, or disassembly of a cellular component. |
|
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:0003824
|
catalytic activity
|
Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
|
GO:0140096
|
catalytic activity, acting on a protein
|
Catalytic activity that acts to modify a protein. |
|
GO:0016491
|
oxidoreductase activity
|
Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
|
GO:0006325
|
chromatin organization
|
The assembly or remodeling of chromatin composed of DNA complexed with histones, other associated proteins, and sometimes RNA. |
|
GO:0006338
|
chromatin remodeling
|
A dynamic process of chromatin reorganization resulting in changes to chromatin structure. These changes allow DNA metabolic processes such as transcriptional regulation, DNA recombination, DNA repair, and DNA replication. |
|
GO:0016705
|
oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen
|
Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from each of two donors, and molecular oxygen is reduced or incorporated into a donor. |
|
GO:0051213
|
dioxygenase activity
|
Catalysis of an oxidation-reduction (redox) reaction in which both atoms of oxygen from one molecule of O2 are incorporated into the (reduced) product(s) of the reaction. The two atoms of oxygen may be distributed between two different products. |
|
GO:0016706
|
2-oxoglutarate-dependent dioxygenase activity
|
Catalysis of the reaction: A + 2-oxoglutarate + O2 = B + succinate + CO2. This is an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from 2-oxoglutarate and one other donor, and one atom of oxygen is incorporated into each donor. |
|
GO:0140993
|
histone modifying activity
|
A catalytic activity that acts on a histone protein. Reversible histone modifications contribute to regulation of gene expression. |
|
GO:0032451
|
demethylase activity
|
Catalysis of the removal of a methyl group from a substrate. |
|
GO:0140457
|
protein demethylase activity
|
Catalysis of the removal of a methyl group from a protein. |
|
GO:0032452
|
histone demethylase activity
|
Catalysis of the removal of a methyl group from a histone. |
|
GO:0141052
|
histone H3 demethylase activity
|
Catalysis of the removal of a methyl group from a modified lysine residue of the histone H3 protein. This is a dioxygenase reaction that is dependent on Fe(II) and 2-oxoglutarate. |
|
GO:0032453
|
histone H3K4 demethylase activity
|
Catalysis of the removal of a methyl group from a modified lysine residue at position 4 of the histone H3 protein. |
|
GO:0034647
|
histone H3K4me/H3K4me2/H3K4me3 demethylase activity
|
Catalysis of the removal of a methyl group from a tri, a di or a monomethyl-lysine residue at position 4 of the histone H3 protein. This is a dioxygenase reaction that is dependent on Fe(II) and 2-oxoglutarate. |
