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.

Translating high-confidence (hc) autism spectrum disorder (ASD) genes into viable treatment targets remains elusive. We constructed a foundational protein-protein interaction (PPI) network in HEK293T cells involving 100 hcASD risk genes, revealing over 1,800 PPIs (87% novel). Interactors, expressed in the human brain and enriched for ASD but not schizophrenia genetic risk, converged on protein complexes involved in neurogenesis, tubulin biology, ... [more]

Quantitative Score

  • 0.988162071 [compPASS Score]

Throughput

  • High Throughput

Additional Notes

  • Affinity purification-MS was used to capture high confidence wild-type protein interactors as defined by the thresholds: BFDR <= 0.05 and compPASS scores (rank_WD) >= 0.971. Baits are Strep-tagged proteins exogenously expressed in HEK 293T cells. ComPASS score: 0.988162071
