Abstract |
Tandem ubiquitin-binding entities (TUBEs) act as molecular traps to isolate polyubiquitylated proteins facilitating the study of this highly reversible posttranslational modification. We provide here sample preparation and adaptations required for TUBE-based enrichment of the ubiquitin proteome from tumor cell lines or primary cells. Our protocol is suitable to identify ubiquitin substrates, enzymes involved in the ubiquitin proteasome pathway, as well as proteasome subunits by mass spectrometry. This protocol was adapted to prepare affinity columns, reduce background, and improve the protein recovery depending on the sample source and necessities. |
