GO term | GO name | GO namespace | GO def |
GO:0038023 | signaling receptor activity | molecular_function | Receiving a signal and transmitting it in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response. [GOC:bf, GOC:signaling] |
GO:0009986 | cell surface | cellular_component | The external part of the cell wall and/or plasma membrane. [GOC:jl, GOC:mtg_sensu, GOC:sm] |
GO:0007166 | cell surface receptor signaling pathway | biological_process | A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription. [GOC:bf, GOC:mah, GOC:pr, GOC:signaling] |
GO:0042113 | B cell activation | biological_process | The change in morphology and behavior of a mature or immature B cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific. [GOC:mgi_curators, ISBN:0781735149] |
GO:0005887 | integral component of plasma membrane | cellular_component | The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. [GOC:dos, GOC:go_curators] |
GO:0060089 | molecular transducer activity | molecular_function | A compound molecular function in which an effector function is controlled by one or more regulatory components. [GOC:dos, GOC:pdt] |
GO:0004888 | transmembrane signaling receptor activity | molecular_function | Combining with an extracellular or intracellular signal and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity or state as part of signal transduction.
