Cascade of at least three protein kinase activities culminating in the phosphorylation and activation of a MAP kinase. MAPKKK cascades lie downstream of numerous signaling pathways [goid 165] [evidence IEA]; The process of introducing a phosphate group on to a protein [goid 6468] [evidence IEA]; A process that directly activates any of the steps required for cell death by apoptosis [goid 6917] [pmid 10958679] [evidence TAS]; The directed movement of a motile cell or organism, or the directed growth of a cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis) [goid 6935] [pmid 10706854] [evidence TAS]; 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 indicating damage to its DNA from environmental insults or errors during metabolism [goid 6974] [evidence IEA]; The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division [goid 7049] [evidence IEA]; A series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state [goid 7265] [pmid 11520933] [evidence EXP]; The process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse [goid 7268] [pmid 10051431] [evidence TAS]; Morphogenesis of an organ. An organ is defined as a tissue or set of tissues that work together to perform a specific function or functions. Morphogenesis is the process by which anatomical structures are generated and organized. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions [goid 9887] [evidence IEA]; The chemical reactions and pathways involving cytosine, 4-amino-2-hydroxypyrimidine, a pyrimidine derivative that is one of the five main bases found in nucleic acids; it occurs widely in cytidine derivatives [goid 19858] [evidence IEA]; The series of molecular signals generated in response to detection of lipopolysaccharide [goid 31663] [evidence IEA]; A change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a of lipopolysaccharide stimulus; lipopolysaccharide is a major component of the cell wall of gram-negative bacteria [goid 32496] [evidence IEA]; 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 an exogenous double-stranded RNA stimulus [goid 43330] [evidence IEA]; Any process by which an organism has an effect on an organism of a different species [goid 44419] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of cell differentiation [goid 45596] [evidence IEA]
