Cross-Linking-MS (XL-MS)
An interaction is detected between two proteins using chemically reactive or photo-activatable cross-linking reagents that covalently link amino acids in close proximity, followed by mass spectrometry analysis to identify the linked peptides (reviewed in PMID 37406423, 37104977). Experiments may be carried with live cells or cell lysates in which all proteins are expressed at endogenous levels (e.g. PMID 34349018, 35235311) or with recombinant proteins (e.g., PMID 28537071).

Protein interaction landscapes revealed by advanced in vivo cross-linking-mass spectrometry.
Defining protein-protein interactions (PPIs) in their native environment is crucial to understanding protein structure and function. Cross-linking-mass spectrometry (XL-MS) has proven effective in capturing PPIs in living cells; however, the proteome coverage remains limited. Here, we have developed a robust in vivo XL-MS platform to facilitate in-depth PPI mapping by integrating a multifunctional MS-cleavable cross-linker with sample preparation strategies and ... [more]
Throughput
- High Throughput
Additional Notes
- In vivo cross-linking-mass spectrometry (XL-MS) was carried out in HEK-293 cells using the cross-linking reagent Alkyne-A-DSBSO (Azide/Alkyne-tagged, acid-cleavable disuccinimidyl bissulfoxide). High confidence protein interactions were identified based on cross-linked peptides having an FDR < 1%.
