molecular function |
| GO:0009927 | | histidine phosphotransfer kinase activity | | Serves as a phospho-His intermediate enabling the transfer of phospho group between a hybrid kinase and a response regulator. |
| GO:0043424 | | protein histidine kinase binding | | Interacting selectively and non-covalently with protein histidine kinase. |
| 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. |
biological process |
| GO:0009736 | | cytokinin-activated signaling pathway | | A series of molecular signals generated by the binding of a cytokinin to a receptor, and ending with regulation of a downstream cellular process, e.g. transcription. |
| GO:0000160 | | phosphorelay signal transduction system | | A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins. |
| GO:0016310 | | phosphorylation | | The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide. |
| GO:0080038 | | positive regulation of cytokinin-activated signaling pathway | | Any process that activates or increases the frequency, rate or extent of cytokinin signaling. |
| GO:0050896 | | response to stimulus | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus. The process begins with detection of the stimulus and ends with a change in state or activity or the cell or organism. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
