Diffusion control of protein phosphorylation in signal transduction pathways.
Multiple signalling proteins are phosphorylated and dephosphorylated at separate cellular locations, which potentially causes spatial gradients of phospho-proteins within the cell. We have derived relationships that enable us to estimate the extent to which a protein kinase, a phosphatase and the diffusion of signalling proteins control the protein phosphorylation flux and the phospho-protein g...
متن کاملRole of protein phosphorylation in neuronal signal transduction.
Protein phosphorylation is involved in the regulation of a wide variety of physiological processes in the nervous system. Studies in which purified protein kinases or kinase inhibitors have been microinjected into defined cells while a specific response is monitored have demonstrated that protein phosphorylation is both necessary and sufficient to mediate responses of excitable cells to extrace...
متن کاملEngineering Signal Transduction Pathways
Cells respond to their environment by sensing signals and translating them into changes in gene expression. In recent years, synthetic networks have been designed in both prokaryotic and eukaryotic systems to create new functionalities and for specific applications. In this review, we discuss the challenges associated with engineering signal transduction pathways. Furthermore, we address advant...
متن کاملProtein phosphorylation and its role in archaeal signal transduction
Reversible protein phosphorylation is the main mechanism of signal transduction that enables cells to rapidly respond to environmental changes by controlling the functional properties of proteins in response to external stimuli. However, whereas signal transduction is well studied in Eukaryotes and Bacteria, the knowledge in Archaea is still rather scarce. Archaea are special with regard to pro...
متن کاملG-protein-dependent and -independent pathways in denatonium signal transduction.
To clarify the involvement of G protein in denatonium signal transduction, we carried out a whole-cell patch-clamp analysis with isolated taste cells in mice. Two different responses were observed by applying GDP-beta-S, a G-protein inhibitor. One response to denatonium was reduced by GDP-beta-S (G-protein-dependent), whereas the other was not affected (G-protein-independent). These different p...
