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.
Publication
53BP1 is associated with replication protein A and is required for RPA2 hyperphosphorylation following DNA damage.
p53-binding protein 1 (53BP1) acts as an 'adaptor/mediator' for transducing DNA damage signals, especially following detection of DNA double-strand breaks. In an effort to broaden our understanding of the protein network surrounding 53BP1, we isolated possible 53BP1 binding partners by co-immunoprecipitation, and identified them via tandem mass spectrometric analysis. The 53BP1-associated proteins included RPA1 and RPA2, two components of the ... [more]

Additional Notes
- Association between 53BP1 and RPA2 was disrupted following DNA damage induced by treatment with camptothecin, a topoisomerase I inhibitor

| TP53BP1 RPA2 | 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. | Low | - | BioGRID | 243796 | |
