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.

Biomolecular condensates are cellular compartments without enveloping membranes, enabling them to dynamically adjust their composition in response to environmental changes through post-translational modifications. Recent work has revealed that interferon-induced ADP-ribosylation (ADPr), which can be reversed by a SARS-CoV-2-encoded hydrolase, is enriched within a condensate. However, the identity of the condensate and the responsible host ADP-ribosyltransferase remain elusive. Here, we demonstrate ... [more]

  • High Throughput

Additional Notes

  • Affinity capture MS was carried out to identify high confidence protein interactors with or without IFN-gamma treatment with enrichment over the IgG control (FDR < 0.1%). This hit was identified in the following condition(s):
  • untreated samples
