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.

Thousands of interactions assemble proteins into modules that impart spatial and functional organization to the cellular proteome. Through affinity-purification mass spectrometry, we have created two proteome-scale, cell-line-specific interaction networks. The first, BioPlex 3.0, results from affinity purification of 10,128 human proteins-half the proteome-in 293T cells and includes 118,162 interactions among 14,586 proteins. The second results from 5,522 immunoprecipitations in HCT116 ... [more]

  • High Throughput

Additional Notes

  • BioPlex HCT HCT116 cells CompPASS score = 0.99999754, threshold = 0.75. Quantitative scores are calculated by CompPASS-Plus (Huttlin et al. Cell 2015, PMID: 26186194). The 0.75 threshold represents the top 2% of scores in HCT116.
  • Only scores from within the same cell line in BioPlex HCT (PMID: 33961781) should be compared directly. For comparison of HEK293T and HCT116 interaction networks with relaxed threshold = 0.1, see BioPlex Interactome (https://bioplex.hms.harvard.edu/index.php).

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.
