Fig. 3. The BUR1 CID enhances BUR1/BUR2 recruitment to the ARG1 5′ ORF in vivo.
(A-C) BUR1::myc strains (HQY1188, HQY1223, HQY1280) and (D) BUR2::myc strains (HQY1002, HQY1003, HQY1268) were subjected to ChIP analysis as described in Fig.1, with representative results shown in (A), and GCN4-dependent occupancies plotted in (C-D). (B) gives the ratio of IP to Inp signals for ARG1, normalized to the corresponding values for the gcn4Δ strain, without normalizing for the ChrV signals.
