(E) Aberrant binding of overexpressed EUC1 partially depends on Euc1 DNA binding. ChIP-qPCR of Euc1 after 3 hours galactose induction. Note that IP/input ratios of Euc1 signals are shown, also for the control locus (contr., TOS1 promoter) to highlight Euc1 binding at non-ub-HS sites. STI1-CIN5: intergenic region. TEC1-us: upstream (promoter) region. Data represent means ± SD (n = 3). See also Fig. EV4C-D.
