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).

EndoMAP.v1 charts the structural landscape of human early endosome complexes.
Early or sorting endosomes are dynamic organelles that play key roles in proteome control by triaging plasma membrane proteins for either recycling or degradation in the lysosome1,2. These events are coordinated by numerous transiently associated regulatory complexes and integral membrane components that contribute to organelle identity during endosome maturation3. Although a subset of the several hundred protein components and cargoes ... [more]

Additional Notes
- High confidence protein interactions had an XlinkX score >40. Re-analysis performed with Scout used a 1% FDR cutoff on Residue Pair level.
- XL-MS analysis of DHSO cross-linked peptides (purified endosomes) using Scout with a 1% FDR cutoff on Residue Pair level.
- XL-MS of two independent replicates cross-linked with DSSO in HEK293 cells.
