Signal Transduction and Targeted Therapy is a multidisciplinary peer-reviewed open access scientific journal covering biomedical research with a particular focus on signal transduction and its application to the drug development process. It was established in 2016 and is published by Nature Research.
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events. Proteins responsible for detecting stimuli are generally termed receptors , although in some cases the term sensor is used. [ 1 ]
Akt target substrates contain a minimum consensus sequence R-X-R-X-X-[Ser/Thr]-Hyd, where Hyd is a hydrophobic amino acid, although other factors such as sub-cellular localisation and 3-dimensional structure are important. [5] Phosphorylation by Akt can be inhibitory or stimulatory, either suppressing or enhancing the activity of target proteins.
This insulin signal transduction pathway is composed of trigger mechanisms (e.g., autophosphorylation mechanisms) that serve as signals throughout the cell. There is also a counter mechanism in the body to stop the secretion of insulin beyond a certain limit. Namely, those counter-regulatory mechanisms are glucagon and epinephrine.
A nuclear localization signal (NLS) is a target peptide that directs proteins to the nucleus and is often a unit consisting of five basic, positively charged amino acids. The NLS normally is located anywhere on the peptide chain. A nuclear export signal (NES) is a target peptide that directs proteins from the nucleus back to the cytosol. It ...
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output. In practice, m is usually chosen to be greater than unity.
The Journal of Receptors and Signal Transduction is a peer-reviewed scientific journal that publishes laboratory and clinical studies, reviews, and brief communications on biological receptors and associated signal transduction pathways for ligands involved in the regulation of central and peripheral tissues and cells.
In signal processing and control theory, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse (δ(t)). More generally, an impulse response is the reaction of any dynamic system in response to some external change.
