ProteomicsProteome solubility changes under different proteostasis stresses
The accumulation of aberrant protein aggregates in neurodegenerative diseases is associated with a widespread failure of the protein homeostasis system. To investigate whether there is a subproteome that consistently aggregates under stress and define the broader determinants for protein aggregation...

ProteomicsIon-based Proteome Integrated Solubility Alteration Assay for System-wide Profiling of Protein-Molecule Interactions - full curve data
Unbiased drug target engagement deconvolution and mechanism of action elucidation are major challenges in drug development. Modification-free target engagement methods, such as thermal proteome profiling, have gained increasing popularity over the last several years. However, these methods have limi...

ProteomicsRNA-dependent solubility of Escherichia coli proteome: Structural hub, disorder, and chaperone network
Protein aggregation is a complex phenomenon involving aberrant folding and proteostasis that leads to various proteopathies. Despite extensive efforts, the maintenance of protein solubility against aggregation remains ill-defined, especially in complex cellular environments. In this study, we show t...

ProteomicsOne-Pot Time-Induced Proteome Integral Solubility Alteration (OPTI-PISA) assay for automated and sensitive drug target identification
Proteome Integral Solubility Alteration (PISA) assay is widely used for identifying drug targets, but it is labour-, sample and time-consuming. Aiming at enabling automation and greatly reducing the sample amount, we developed One-Pot Time-Induced (OPTI)-PISA. Here we demonstrate OPTI-PISA performan...
