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%.

| PPP2R1B PPP2R1A | Affinity Capture-Western Affinity Capture-Western An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins. | Low | - | BioGRID | - | |
