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]

Additional Notes

  • BioPlex 3.0 HEK 293T cells CompPASS score = 0.987614733, 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 HEK293T.
  • This data may be re-scored from BioPlex 1.0 (PMID: 26186194) and BioPlex 2.0 (PMID: 28514442). Only scores from within the same cell line in BioPlex 3.0 (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).
