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.

Mitochondria are essential organelles whose functions depend on coordinated multiprotein complexes, yet their composition and organization remain incomplete. Here, we present a large-scale map of mitochondrial protein complexes by integrating affinity purification of 740 endogenously GFP-tagged mitochondrial proteins with biochemical co-fractionation of mitochondrial extracts from yeast (Saccharomyces cerevisiae) grown under respiratory conditions. Mass spectrometry identifies 13,716 high-confidence protein associations and ... [more]

Quantitative Score

  • 6.13 [Confidence Score]

Throughput

  • High Throughput

Additional Notes

  • High throughput score cut-off value/description The PPIs are derived from two methods AP-MS and CF-MS. The LLS PPI score is derived from the LLS AP-MS and LLS CF-MS scores. The cutoff for AP-MS is 5.34 and CF-MS is 3.12. If the PPI is detected by both methods and meets the threshold in one of the methods the Average LLS score is taken as the final LLS score for the PPI.

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.

Co-fractionation
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.
