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.

Compartmentalization is a defining characteristic of eukaryotic cells, and partitions distinct biochemical processes into discrete subcellular locations. Microscopy1 and biochemical fractionation coupled with mass spectrometry2-4 have defined the proteomes of a variety of different organelles, but many intracellular compartments have remained refractory to such approaches. Proximity-dependent biotinylation techniques such as BioID provide an alternative approach to define the composition of ... [more]

Additional Notes

BioID
SAINTexpress (v.3.6.1) was used to identify proximity interactions and those with a Bayesian FDR =< 0.01 were considered high confidence. The score represents the fold change of the average spectral count in sample replicates relative to the average in control replicates.
