ProteomicsAn Amphibious Bi-functional Probe For Protein Chemical Cross-linking.
Chemical cross-linking mass spectrometry (CXMS) has emerged as a powerful and well-established method for probing protein structure, conformational dynamics, and protein–protein interactions, particularly in cases where classical high-resolution techniques face intrinsic limitations. The development...

ProteomicsIdentification of human PKD2 interaction partners from cytosolic protein fractions of HeLa cells by affinity enrichment cross-linking/MS
We investigated the interaction network of human PKD2 in the cytosol as well as in Golgi-enriched subcellular protein fractions, using an affinity enrichment strategy combined with chemical cross-linking/mass spectrometry (MS). Analysis of the subproteomes revealed the presence of distinct proteins ...

ProteomicsInteractions of CDK19 with MED12 and cyclin-C assessed by chemical cross-linking mass spectrometry
Chemical cross-linking coupled to mass spectrometry was used to study binary and ternary complexes involving cyclin-dependent kinase 19 (CDK19), cyclin-C, and an N-terminal fragment of subunit 12 of the Mediator complex (MED12 1-100). Cross-linking was performed using disuccinimidyl suberate (DSS). ...

ProteomicsFolding of beta-tubulin by the chaperonin TRiC/CCT studied by chemical cross-linking and mass spectrometry
Chemical cross-linking coupled to mass spectrometry was used to study the folding of the client protein, beta-tubulin, by the chaperonin TRiC/CCT. Different complexes containing TRiC/CCT and/or the chaperone prefoldin were cross-linked in absence or presence of nucleotides with the homobifunctional,...

ProteomicsStructure of Cyanobacterial Phycobilisome Core Revealed by Structural Modeling and Chemical Cross-linking
In cyanobacteria and red algae, the structural basis dictating efficient excitation energy transfer from the phycobilisome (PBS) antenna complex to the reaction centers (RCs) remains unclear. PBS has several peripheral rods and a central core, which binds to the thylakoid membrane, allowing energy c...

ProteomicsCharacterizing the dynamic oligomerization of Hsp90β using photo-cross-linking
Cross-linking mass spectrometry (XL-MS) is a powerful tool for probing protein structures. While conventional chemical cross-linkers react with specific residues with defined chemistry, photo-cross-linkers, despite their superior reactivity, have been hindered by incomplete mechanistic understanding...

ProteomicsOn the reproducibility of label-free quantitative cross-linking/mass spectrometry
Quantitative cross-linking/mass spectrometry (QCLMS) is an emerging approach to study conformational changes of proteins and multi-subunit complexes. Distinguishing protein conformations requires reproducibly identifying and quantifying cross-linked peptides. Here we analyzed the variation between m...
