Ubiquitinated targets of VAPB and FAF1 identified by mass spectrometry upon enrichment of ubiquitinated peptides. A mixture of light-labeled Flag-VAPB and heavy-labeled Flag-FAF1 immunoprecipitates was analyzed by mass spectrometry after ubiquitinated peptide enrichment using antibodies specific to lysine-ϵ-GlyGly. The peptides containing lysine residues with an additional MW due to the GlyGly modification – 250.15 (heavy label) or 242.14 (light label) – are indicated for each protein.
