1. Concern about Figure 1C.
Horizontal lines are visible in the bottom part of the left panel, and the top part of the right panel, with a sudden change in background coloring and patterns. They are positioned at the exact spot where interesting protein complexes could have been present.

Concern about Figure 4B and 4C.
In the top panel of Figure 4B-b, a cut appears to be visible between the left and right half of the blot image.
In the bottom panel of Figure 4B-b, a horizontal “patch” appears to be visible, with a lighter background than the rest of the blot.
In Figure 4C, vertical lines are visible.

Concern about Figure 5A. Two vertical cuts appear to be visible between the lanes 1 and 2, and lanes 4 and 5 of all three panels, suggesting these samples might not have been run on the same gel. In the Cdc34 delta panel, lane 1 appears very similar to lane 5.

Concern about Figure 6C-b. A vertical cut appears to be visible between the lanes 1 and 2 of both the top and bottom panel, suggesting these samples might not have been run on the same gel.
