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.

Proteomic analysis of the cullin 4B interactome using proximity-dependent biotinylation in living cells.

Zhang H, Li S, Liu P, Lee FHF, Wong AHC, Liu F

Cullin 4B (CUL4B) mutations have been implicated in mental retardation and dopamine-related behaviors due to disruptions in their interaction with cullin-RING E3 ligases (CRLs). Thus, further identification of CUL4B substrates can increase the knowledge of protein homeostasis and illuminate the role of CUL4B in neuropsychiatric disease. However, the transient nature of the coupling between CUL4B and its substrates is difficult ... [more]
