ProteomicsStrategies to enhance the extraction of electrophoretically separated proteins from polyacrylamide gels and their application to mass spectrometry analyses (C4PR_LIV)
Polyacrylamide gel electrophoresis (PAGE) is a powerful technique for separating proteins extracted from complex biological samples. Unfortunately, the difficulty of recovering intact proteins in high yield from polyacrylamide matrices often limits further analyses. We discovered that staining prote...

ProteomicsThe Expanding Landscape of Human Protein Phosphorylation C4PR_LIV
Investigation of protein phosphorylation in humans has largely focussed on serine (Ser), threonine (Thr) and tyrosine (Tyr), with proven roles for these modifications in all aspects of life. However, mounting evidence suggests that phosphorylation of non-canonical amino acids, including histidine an...

ProteomicsProteomic analysis of dietary restriction in yeast reveals a role for Hsp26 in lifespan extension C4PR_LIV
Dietary restriction (DR) has been shown to increase lifespan in organisms ranging from yeast to mammals. This suggests that the underlying mechanisms may be evolutionarily conserved. Indeed, upstream signalling pathways, such as TOR, are strongly linked to DR-induced longevity in various organisms. ...

ProteomicsUse of the Polo-like kinase 4 (PLK4) inhibitor centrinone to investigate intracellular signaling networks using SILAC-based phosphoproteomics_C4PR
Polo-like kinase 4 (PLK4) is the master regulator of centriole duplication in metazoan organisms. Catalytic activity and protein turnover of PLK4 are tightly coupled in human cells, since changes in PLK4 concentration and catalysis have profound effects on centriole duplication and supernumerary cen...

ProteomicsC4PR_LIV Evaluation of Parameters for Confident Phosphorylation Site Localization using an Orbitrap Fusion Tribrid Mass Spectrometer
Confident identification of sites of protein phosphorylation by mass spectrometry (MS) is essential to advance understanding of phosphorylation-mediated signaling events. However, development of novel instrumentation requires that methods for MS data acquisition and its interrogation be evaluated an...
