Post-translational Modifications of the Protein Termini [PDF]
Frontiers in Cell and Developmental Biology, 2021 Post-translational modifications (PTM) involve enzyme-mediated covalent addition of functional groups to proteins during or after synthesis. These modifications greatly increase biological complexity and are responsible for orders of magnitude change between the variety of proteins encoded in the genome and the variety of their biological functions ...

Post translational modification of Parkin [PDF]
Biology Direct, 2017 Mutations in the gene encoding for the E3 ubiquitin ligase Parkin are associated to a rare form of familiar autosomal recessive Parkinsonism. Despite decades of research on the Parkin protein, whose structure has been recently solved, little is known about the specific signalling pathways that lead to Parkin activation.

Post-translational modifications of microtubules [PDF]
Journal of Cell Science, 2010 Microtubules – polymers of tubulin – perform essential functions, including regulation of cell shape, intracellular transport and cell motility. How microtubules are adapted to perform multiple diverse functions is not well understood. Post-translational modifications of tubulin subunits diversify the outer and luminal surfaces of microtubules and ...

Post-translational modifications of tubulin [PDF]
Current Biology, 2014 Microtubules are the largest filamentous components of the eukaryotic cytoskeleton. In spite of their extraordinary level of structural conservation, microtubules fulfill a vast range of different functions in cells. How this functional diversity is achieved remains an open question; however, recent advances point towards post-translational ...

Post-Translational Modifications of ATG4B in the Regulation of Autophagy
Cells, 2022 Autophagy plays a key role in eliminating and recycling cellular components in response to stress, including starvation. Dysregulation of autophagy is observed in various diseases, including neurodegenerative diseases, cancer, and diabetes.

Post-translational modification by SUMO [PDF]
Toxicology, 2010 Post-translational modifications (PTMs) are chemical alterations to a protein following translation, regulating stability and function. Reversible phosphorylation is an example of an important and well studied PTM involved in a number of cellular processes.

Sirtuin Oxidative Post-translational Modifications [PDF]
Frontiers in Physiology, 2021 Increased sirtuin deacylase activity is correlated with increased lifespan and healthspan in eukaryotes. Conversely, decreased sirtuin deacylase activity is correlated with increased susceptibility to aging-related diseases. However, the mechanisms leading to decreased sirtuin activity during aging are poorly understood.

Subcellular trafficking and post-translational modification regulate PIN polarity in plants
Frontiers in Plant Science, 2022 Auxin regulates plant growth and tropism responses. As a phytohormone, auxin is transported between its synthesis sites and action sites. Most natural auxin moves between cells via a polar transport system that is mediated by PIN-FORMED (PIN) auxin ...

Post-Translational Modifications of Extracellular Proteasome [PDF]
Molecules, 2020 The ubiquitin-proteasome system (UPS) is one of the major protein degradation pathways in eukaryotic cells. Abnormal functioning of this system has been observed in cancer and neurological diseases. The 20S proteasomes, essential components of the UPS, are present not only within the cells but also in the extracellular space, and their concentration in
