FunFam 25: Histidine kinase 1-like protein

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 5 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
2 O22267 (/IPI) Q9SXL4 (/IPI)
Protein histidine kinase activity GO:0004673
Catalysis of the reaction: ATP + protein L-histidine = ADP + protein phospho-L-histidine.
1 O22267 (/IDA)
Osmosensor activity GO:0005034
Sensing extracellular osmolarity to initiate a change in cell activity, and spanning the membrane of the cell.
1 Q9SXL4 (/IMP)
Histidine phosphotransfer kinase activity GO:0009927
Serves as a phospho-His intermediate enabling the transfer of phospho group between a hybrid kinase and a response regulator.
1 Q9SXL4 (/IMP)
Protein homodimerization activity GO:0042803
Interacting selectively and non-covalently with an identical protein to form a homodimer.

GO Term Annotations Evidence
Response to osmotic stress GO:0006970
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 indicating an increase or decrease in the concentration of solutes outside the organism or cell.
1 Q9SXL4 (/IMP)
Response to water deprivation GO:0009414
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 water deprivation stimulus, prolonged deprivation of water.
1 Q9SXL4 (/IEP)
Response to water deprivation GO:0009414
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 water deprivation stimulus, prolonged deprivation of water.
1 Q9SXL4 (/IMP)
Embryo sac development GO:0009553
The process whose specific outcome is the progression of the embryo sac over time, from its formation to the mature structure. The process begins with the meiosis of the megasporocyte to form four haploid megaspores. Three of the megaspores disintegrate, and the fourth undergoes mitosis giving rise to a binucleate syncytial embryo sac. The two haploid nuclei migrate to the opposite poles of the embryo sac and then undergo two rounds of mitosis generating four haploid nuclei at each pole. One nucleus from each set of four migrates to the center of the cell. Cellularization occurs, resulting in an eight-nucleate seven-celled structure. This structure contains two synergid cells and an egg cell at the micropylar end, and three antipodal cells at the other end. A binucleate endosperm mother cell is formed at the center. The two polar nuclei fuse resulting in a mononucleate diploid endosperm mother cell. The three antipodal cells degenerate.
1 O22267 (/IMP)
Cytokinin-activated signaling pathway GO:0009736
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.
1 O22267 (/TAS)
Phloem or xylem histogenesis GO:0010087
The process whose specific outcome is the progression of phloem and/or xylem over time, from formation to the mature structure. An example of this process is found in Arabidopsis thaliana.
1 O22267 (/IMP)
Stomatal complex patterning GO:0010375
The regionalization process of establishing the non-random spatial arrangement of stomatal complex on the surface of a leaf. The stomatal complex is the stomatal guard cells and their associated epidermal cells.
1 Q9SXL4 (/IMP)
Seed maturation GO:0010431
A process in seed development that occurs after embryogenesis by which a quiescent state is established in a seed. Seed maturation is characterized by storage compound accumulation, acquisition of desiccation tolerance, growth arrest and the entry into a dormancy period of variable length that is broken upon germination.
1 Q9SXL4 (/IMP)
Secondary growth GO:0080117
Lateral growth of a plant axis (shoot axis or root) that is an increase in thickness resulting from formation of secondary vascular tissues by the vascular cambium.
1 O22267 (/IMP)
