EOG808QP3 GO:0007165 6/22 signal transduction biological_process "The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell."

[GOC:go_curators] EOG808QP3 GO:0007275 3/22 multicellular organismal development biological_process "The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult)." [GOC:dph, GOC:ems, GOC:isa_complete, GOC:tb] EOG808QP3 GO:0008270 3/22 zinc ion binding molecular_function "Interacting selectively and non-covalently with zinc (Zn) ions." [GOC:ai] EOG808QP3 GO:0005634 3/22 nucleus cellular_component "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." [GOC:go_curators] EOG808QP3 GO:0004842 3/22 ubiquitin-protein transferase activity molecular_function "Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages."

[GOC:dos, GOC:go_curators] EOG808QP3 GO:0006955 1/22 immune response biological_process "Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat." [GO_REF:0000022, GOC:add, GOC:mtg_15nov05] EOG808QP3 GO:0004888 1/22 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." [GOC:go_curators, Wikipedia:Transmembrane_receptor] EOG808QP3 GO:0002224 1/22 toll-like receptor signaling pathway biological_process "Any series of molecular signals generated as a consequence of binding to a toll-like receptor. Toll-like receptors directly bind pattern motifs from a variety of microbial sources to initiate innate immune response."
