Affinity Capture-MS

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 is identified by mass spectrometric methods.

As part of an ongoing effort led by Steve Gygi, Wade Harper, and Ed Huttlin in the Department of Cell Biology at Harvard Medical School, we are systematically profiling the interactions among human proteins using affinity purification mass spectrometry. In this effort, HA-tagged bait proteins obtained from the human ORFeome collection (version 8.1; Marc Vidal) are expressed individually in human ... [more]

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.

Cross-Linking-MS (XL-MS)
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).
