Proximity Label-MS

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.

Viral replication is dependent on interactions between viral polypeptides and host proteins. Identifying virus-host protein interactions can thus uncover unique opportunities for interfering with the virus life cycle via novel drug compounds or drug repurposing. Importantly, many viral-host protein interactions take place at intracellular membranes and poorly soluble organelles, which are difficult to profile using classical biochemical purification approaches.

  • High Throughput

Additional Notes

  • BioID
  • SAINTexpress (v.3.6.1) was used to identify viral-host proximity interactions and those with an FDR =< 0.01 were considered high confidence. Control-subtracted and length-adjusted spectral counts (CLSC) were calculated and the top viral-host protein interactions are represented by a higher CLSC score.
