Mps1 is required to phosphorylate BubR1 in cells. Cells transfected with control, and Mps1 siRNA were released from a double thymidine block. MG132 was added 8 h later, and mitotic cells were harvested 2 h later by shakeoff. Lysates were probed with all four phospho-BubR1 antibodies. Two different amounts of control lysates were used, so it was possible to directly compare the band intensities with Mps1-depleted lysate. CENP-F, BubR1, and cyclin B1 were used as loading controls.
