Synthetic post-translational modification of histones

Allosteric post-translational modification codes.

Post-translational modifications (PTMs) have been recognized to impact protein function in two ways: (i) orthosterically, via direct recognition by protein domains or through interference with binding; and (ii) allosterically, via conformational changes induced at the functional sites. Because different chemical types of PTMs elicit different structural alterations, the effects of combinatorial...

Post-translational modification by SUMO.

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. SUMOylation is another PTM known to modify a large number of proteins and plays a role in various cellular processes including: cell cycle ...

Global Post-Translational Modification Discovery

A new global post-translational modification (PTM) discovery strategy, G-PTM-D, is described. A proteomics database containing UniProt-curated PTM information is supplemented with potential new modification types and sites discovered from a first-round search of mass spectrometry data with ultrawide precursor mass tolerance. A second-round search employing the supplemented database conducted wi...

Post-Translational Modifications of Histones in Vertebrate Neurogenesis

The process of neurogenesis, through which the entire nervous system of an organism is formed, has attracted immense scientific attention for decades. How can a single neural stem cell give rise to astrocytes, oligodendrocytes, and neurons? Furthermore, how is a neuron led to choose between the hundreds of different neuronal subtypes that the vertebrate CNS contains? Traditionally, niche signal...
