a, Surface conservation plot of S. cerevisiae Ycg1–Brn1 (left). Tetrad dissection of diploid S. cerevisiae YCG1/ycg1Δ cells expressing an ectopic PK6-tagged copy of Ycg1 harboring patch 1 or patch 2 mutations, after three days on rich media at 25 °C for 3 days (center). Expression levels of Ycg1-PK6 tested by Western blotting against the PK6 tag (right). b, Western blot analysis of photo-crosslinking products expressing Ycg1-PK6 with bpa substitutions at the indicated residues before (–UV) or after (+UV) exposure to light at 365 nm (left). Shift of endogenously HA-tagged versions Smc4, Smc2, Ycg1 or Brn1 in cells expressing unmodified wild-type (wt) or bpa-substituted Ycg1 at position S435 measured by Western blotting before (–UV) or after (+UV) light exposure (right).
