Wss1 binding interactions. (A) Schematic representation of Psy2 and Tof1 protein sequences. Regions recovered form yeast two-hybrid screen are shaded in gray. (B and C) Direct yeast two-hybrid assays. In all cases, both bait and prey constructs are expressed. (B) Growth on Leu− medium indicates a binding interaction. (C) Growth in the presence of X-gal results in blue color in the presence of a productive binding interaction.
