SGTA interacting partners 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 followed by interrogating the reviewed human UniProt database for SGTA interacting partners. Identified proteins known to interact with SGTA are indicated together with the spectral counts. SGTA peptides detected reflect comparative efficiency for the coupling of SGTA or the mutants to beads.
