4 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. |
pericentriolar material | A network of small fibers that surrounds the centrioles in cells; contains the microtubule nucleating activity of the centrosome. |
6 GO annotations of molecular function
Name | Definition |
---|---|
ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
non-membrane spanning protein tyrosine kinase activity | Catalysis of the reaction |
protein serine/threonine phosphatase activity | Catalysis of the reaction |
protein tyrosine kinase activity | Catalysis of the reaction |
SH2 domain binding | Binding to a SH2 domain (Src homology 2) of a protein, a protein domain of about 100 amino-acid residues and belonging to the alpha + beta domain class. |
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. |
10 GO annotations of biological process
Name | Definition |
---|---|
activation of cysteine-type endopeptidase activity involved in apoptotic process | Any process that initiates the activity of the inactive enzyme cysteine-type endopeptidase in the context of an apoptotic process. |
B cell receptor signaling pathway | The series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell. |
innate immune response | Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
intracellular zinc ion homeostasis | A homeostatic process involved in the maintenance of a steady state level of zinc ions within a cell. |
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. |
positive regulation of intrinsic apoptotic signaling pathway | Any process that activates or increases the frequency, rate or extent of intrinsic apoptotic signaling pathway. |
positive regulation of T cell activation | Any process that activates or increases the frequency, rate or extent of T cell activation. |
response to xenobiotic 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 from a xenobiotic, a compound foreign to the organim exposed to it. It may be synthesized by another organism (like ampicilin) or it can be a synthetic chemical. |
T cell differentiation | The process in which a precursor cell type acquires characteristics of a more mature T-cell. A T cell is a type of lymphocyte whose definin characteristic is the expression of a T cell receptor complex. |
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. |
