Signal-transduction networks and the regulation of muscle protein degradation.
Protein degradation in muscle functions in maintaining normal physiological homeostasis and adapting to new homeostatic states, and is required for muscle wasting or atrophy in various pathological states. The interplay between protein synthesis and degradation to maintain homeostasis is complex and responds to a variety of autocrine and intercellular signals from neuronal inputs, hormones, cyt...
متن کاملSignal transduction through prion protein.
The cellular prion protein PrPc is a glycosylphosphatidylinositol-anchored cell-surface protein whose biological function is unclear. We used the murine 1C11 neuronal differentiation model to search for PrPc-dependent signal transduction through antibody-mediated cross-linking. A caveolin-1-dependent coupling of PrPc to the tyrosine kinase Fyn was observed. Clathrin might also contribute to thi...
متن کاملSignal transduction: Gyrating protein kinases
Recently determined structures have linked histidine kinases with class II topoisomerases, the DNA repair enzyme MutL and the molecular chaperone Hsp90. This surprising finding may foreshadow a shift in our understanding of energy coupling mechanisms in signal transduction networks.
متن کاملRegulation of Signal Transduction by Glutathione Transferases
Glutathione transferases (GST) are essentially known as enzymes that catalyse the conjugation of glutathione to various electrophilic compounds such as chemical carcinogens, environmental pollutants, and antitumor agents. However, this protein family is also involved in the metabolism of endogenous compounds which play critical roles in the regulation of signaling pathways. For example, the lip...
متن کاملRegulation of signal transduction by endocytosis.
Endocytosis of ligand-activated receptors has generally been considered a mechanism to attenuate signaling. There is now a growing body of evidence suggesting that this process is much more sophisticated and that endocytic membrane trafficking regulates both the intensity of signaling and the co-localization of activated receptors with downstream signaling molecules.
