5 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| extrinsic component of cytoplasmic side of plasma membrane | The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region. |
| membrane raft | Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions. |
| 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. |
| perikaryon | The portion of the cell soma (neuronal cell body) that excludes the nucleus. |
7 GO annotations of molecular function
| Name | Definition |
|---|---|
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| metal ion binding | Binding to a metal ion. |
| non-membrane spanning protein tyrosine kinase activity | Catalysis of the reaction |
| protein kinase activity | Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction |
| protein tyrosine kinase activity | Catalysis of the reaction |
| signaling receptor binding | Binding to one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. |
| tubulin binding | Binding to monomeric or multimeric forms of tubulin, including microtubules. |
7 GO annotations of biological process
| Name | Definition |
|---|---|
| cell differentiation | The cellular developmental process in which a relatively unspecialized cell, e.g. embryonic or regenerative cell, acquires specialized structural and/or functional features that characterize a specific cell. Differentiation includes the processes involved in commitment of a cell to a specific fate and its subsequent development to the mature state. |
| forebrain development | The process whose specific outcome is the progression of the forebrain over time, from its formation to the mature structure. The forebrain is the anterior of the three primary divisions of the developing chordate brain or the corresponding part of the adult brain (in vertebrates, includes especially the cerebral hemispheres, the thalamus, and the hypothalamus and especially in higher vertebrates is the main control center for sensory and associative information processing, visceral functions, and voluntary motor functions). |
| innate immune response | Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
| neuron migration | The characteristic movement of an immature neuron from germinal zones to specific positions where they will reside as they mature. |
| peptidyl-tyrosine phosphorylation | The phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine. |
| regulation of cell shape | Any process that modulates the surface configuration of a cell. |
| transmembrane receptor protein tyrosine kinase signaling pathway | The series of molecular signals initiated by an extracellular ligand binding to a receptor on the surface of the target cell where the receptor possesses tyrosine kinase activity, and ending with the regulation of a downstream cellular process, e.g. transcription. |
