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]

Additional Notes

  • APMS data generated in HEK293T by overexpression of Strep-tagged patient derived ASD variant. Intensity of the interaction between the WT protein and the hit protein was compared to the intensity of the interaction between the patient derived variant and hit protein. Significant interaction intensity changes were defined as those with a log2(fold-change) >= 1 and p <= 0.05. Strengthened interactions were denoted as 'Up', weakened interactions were denoted as 'Down' and unchanged interactions were denoted as 'Not significant' based on these scores. ASD variant: Bait protein name: A251T - Interaction Strength: up, Log2fc: 1.80834318236595, p-value: 0.0164253540091823

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.
