---|---|
cytoskeleton | A cellular structure that forms the internal framework of eukaryotic and prokaryotic cells. The cytoskeleton includes intermediate filaments, microfilaments, microtubules, the microtrabecular lattice, and other structures characterized by a polymeric filamentous nature and long-range order within the cell. The various elements of the cytoskeleton not only serve in the maintenance of cellular shape but also have roles in other cellular functions, including cellular movement, cell division, endocytosis, and movement of organelles. |
cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
endomembrane system | A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles. |
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. |

35 GO annotations of biological process
Name | Definition |
---|---|
adaptive immune response | An immune response mediated by cells expressing specific receptors for antigens produced through a somatic diversification process, and allowing for an enhanced secondary response to subsequent exposures to the same antigen (immunological memory). |
B cell differentiation | The process in which a precursor cell type acquires the specialized features of a B cell. A B cell is a lymphocyte of B lineage with the phenotype CD19-positive and capable of B cell mediated immunity. |
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. |
cellular response to cytokine stimulus | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a cytokine stimulus. |
cytokine-mediated signaling pathway | The series of molecular signals initiated by the binding of a cytokine to a receptor on the surface of a cell, and ending with the regulation of a downstream cellular process, e.g. transcription. |
enzyme-linked receptor protein 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 catalytic activity or is closely associated with an enzyme such as a protein kinase, and ending with the regulation of a downstream cellular process, e.g. transcription. |
growth hormone receptor signaling pathway via JAK-STAT | The process in which STAT proteins (Signal Transducers and Activators of Transcription) are activated by members of the JAK (janus activated kinase) family of tyrosine kinases, following the binding of physiological ligands to the growth hormone receptor. Once activated, STATs dimerize and translocate to the nucleus and modulate the expression of target genes. |
innate immune response | Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
interleukin-15-mediated signaling pathway | The series of molecular signals initiated by interleukin-15 binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription. |

interleukin-4-mediated signaling pathway | The series of molecular signals initiated by interleukin-4 binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription. |
interleukin-9-mediated signaling pathway | The series of molecular signals initiated by interleukin-9 binding to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription. |
intracellular signal transduction | The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell. |
negative regulation of dendritic cell cytokine production | Any process that stops, prevents, or reduces the frequency, rate, or extent of dendritic cell cytokine production. |

receptor signaling pathway via JAK-STAT | Any process in which STAT proteins (Signal Transducers and Activators of Transcription) and JAK (Janus Activated Kinase) proteins convey a signal to trigger a change in the activity or state of a cell. The receptor signaling pathway via JAK-STAT begins with activation of a receptor and proceeeds through STAT protein activation by members of the JAK family of tyrosine kinases. STAT proteins dimerize and subsequently translocate to the nucleus. The pathway ends with regulation of target gene expression by STAT proteins. |
regulation of apoptotic process | Any process that modulates the occurrence or rate of cell death by apoptotic process. |
regulation of T cell apoptotic process | Any process that modulates the occurrence or rate of T cell death by apoptotic process. |
