Post-translational modification and proteolytic processing of urinary osteopontin.

OPN (osteopontin) is a highly phosphorylated glycoprotein present in many tissues and body fluids. In urine, OPN is a potent inhibitor of nucleation, growth and aggregation of calcium oxalate crystals, suggesting that it has a role in the prevention of renal stone formation. The role of OPN in nephrolithiasis is, however, somewhat unclear, as it may also be involved in urinary stone formation, ...

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...

Evidence fore biosynthesis and differential post-translational proteolytic processing of different (pre)prosomatostatins in pancreatic islets.

In anglerfish (AF) pancreatic islets, somatostatin-14 (88-14) is synthesized via a precursor-product pathway. Sequence analyses of cDNAs prepared from AF islet mRNA have demonstrated the presence of mRNAs coding for three different AF preprosomatostatins. From these sequences it was predicted that two of the three precursors contain SS-14 at their COOH terminus whereas the third has an analog f...
