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.

The social and structural architecture of the yeast protein interactome.

Cellular functions are mediated by protein-protein interactions, and mapping the interactome provides fundamental insights into biological systems. Affinity purification coupled to mass spectrometry is an ideal tool for such mapping, but it has been difficult to identify low copy number complexes, membrane complexes and complexes that are disrupted by protein tagging. As a result, our current knowledge of the interactome ... [more]

Quantitative Score

  • 7.0 [Score_FDR+correlation]

Throughput

  • High Throughput

Additional Notes

  • Protein interactions were identified using statistically significant enrichment of the proteins in the forward and reverse pull-downs, as well as making use of the profile similarities of interacting proteins in a correlation analysis. High confidence interactions have a total score >=2. This score is a sum of the FDR score of the forward pull-down + FDR score of the reverse pull-down + correlation score.

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
