The process whereby an activated neuronal cell receptor conveys information down a signaling pathway, resulting in a change in the function or state of a cell. This process may be intracellular or intercellular. The series of molecular signals that bring about the relay, amplification or dampening of a signal generated in response to a cue, such as starvation or pheromone exposure, in organisms that undergo conjugation with cellular fusion. A signal transduction-based surveillance mechanism that ensures accurate chromosome replication and segregation by preventing progression through a mitotic cell cycle until conditions are suitable for the cell to proceed to the next stage. Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Any biological process involved in the generation, transmission, reception, or interpretation of a signal. A signal is an entity used to transmit or convey information. The process whereby a signal is released and/or conveyed from one location to another. Any process that activates or increases the frequency, rate or extent of signal transduction. Any process that modulates the frequency, rate or extent of signal transduction. The cascade of processes by which a signal interacts with a receptor, causing a change in the activity of a SMAD protein, and ultimately effecting a change in the functioning of the cell. The cascade of processes by which a signal interacts with a receptor, causing a change in the level or activity of a second messenger or other downstream target, and ultimately modulating the rate, or extent of floral organ abscission. The process whereby 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. The process whereby an activated receptor conveys information down the signaling pathway, resulting in a change in the function or state of a cell. Any process that modulates the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. Relaying of environmental signals promoting filamentous growth. Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. A signal transduction based surveillance mechanism that prevents the initiation of mitosis until DNA replication is complete, thereby ensuring that progeny inherit a full complement of the genome. A signal transduction-based surveillance mechanism that ensures accurate chromosome replication and segregation by preventing progression through a meiotic cell cycle until conditions are suitable for the cell to proceed to the next stage. Any process that stops, prevents or reduces the frequency, rate or extent of signal transduction. A signal transduction pathway, induced by DNA damage, that blocks cell cycle progression (in G1, G2 or metaphase) or slows the rate at which S phase proceeds. The process whereby a signal causes activation of a receptor, for example, via a conformation change. The sequence of reactions within a cell required to convert absorbed photons into a molecular signal. A signal transduction process resulting in the relay, amplification or dampening of a signal generated in response to pheromone exposure in organisms that undergo conjugation without cellular fusion.
