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.

Comparative Application of BioID and TurboID for Protein-Proximity Biotinylation.

May DG, Scott KL, Campos AR, Roux KJ

BioID is a well-established method for identifying protein-protein interactions and has been utilized within live cells and several animal models. However, the conventional labeling period requires 15-18 h for robust biotinylation which may not be ideal for some applications. Recently, two new ligases termed TurboID and miniTurbo were developed using directed evolution of the BioID ligase and were able to ... [more]
