GO:0004672
|
protein kinase activity
|
Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP. |
|
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:0016301
|
kinase activity
|
Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule. |
|
GO:0016773
|
phosphotransferase activity, alcohol group as acceptor
|
Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor). |
|
GO:0004674
|
protein serine/threonine kinase activity
|
Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. |
|
GO:0016740
|
transferase activity
|
Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
|
GO:0016772
|
transferase activity, transferring phosphorus-containing groups
|
Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to another (acceptor). |
|
GO:0004871
|
signal transducer activity
|
Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. |
|
GO:0004707
|
MAP kinase activity
|
Catalysis of the reaction: protein + ATP = protein phosphate + ADP. This reaction is the phosphorylation of proteins. Mitogen-activated protein kinase; a family of protein kinases that perform a crucial step in relaying signals from the plasma membrane to the nucleus. They are activated by a wide range of proliferation- or differentiation-inducing signals; activation is strong with agonists such as polypeptide growth factors and tumor-promoting phorbol esters, but weak (in most cell backgrounds) by stress stimuli. |
|
GO:0003674
|
molecular_function
|
Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
|
GO:0005057
|
receptor signaling protein activity
|
Conveys a signal from an upstream receptor or intracellular signal transducer, converting the signal into a form where it can ultimately trigger a change in the state or activity of a cell. |
|
GO:0060089
|
molecular transducer activity
|
The molecular function that accepts an input of one form and creates an output of a different form. |
|
GO:0004702
|
receptor signaling protein serine/threonine kinase activity
|
Conveys a signal from an upstream receptor or intracellular signal transducer by catalysis of the reaction: ATP protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. |
