Putative SGTA interacting DUBs identified by mass spectrometry.

Pull-down experiments were performed as described in Materials and Methods. The beads were then analysed for bound proteins by mass spectrometry as detailed in the materials and methods. All DUBs identified from the mass spectrometry are shown together with the spectral counts. The DUBs highlighted were prioritised for further studies based on high spectral counts and low background in the negative control.
