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...
متن کاملPost-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 ...
متن کاملGlobal 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...
متن کاملDeciphering Human Heat Shock Transcription Factor 1 Regulation via Post-Translational Modification in Yeast
Heat shock transcription factor 1 (HSF1) plays an important role in the cellular response to proteotoxic stresses. Under normal growth conditions HSF1 is repressed as an inactive monomer in part through post-translation modifications that include protein acetylation, sumoylation and phosphorylation. Upon exposure to stress HSF1 homotrimerizes, accumulates in nucleus, binds DNA, becomes hyper-ph...
متن کاملPotential Protein Post-translational Modification in Adiponectin
Post-translational modifications of proteins control many biological processes. This is also an important process in the pathogenesis of diabetes mellitus. Adiponectin is an insulin-sensitizing adipokine with antidiabetic, anti-atherogenic, anti-inflammatory and cardioprotective properties. The role of posttranslational modifications in regulating the biosynthesis of high molecular weight adipo...
