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.

Cullin-RING finger ligases (CRLs) represent the largest family of ubiquitin ligases. They are responsible for the ubiquitination of ?20% of cellular proteins degraded through the proteasome, by catalyzing the transfer of E2-loaded ubiquitin to a substrate. Seven Cullins are described in vertebrates. Among them, CUL4 associates with DDB1 to form the CUL4-DDB1 ubiquitin ligase complex, which is involved in protein ... [more]
