Volume 18, Issue 8, Pages 566-575 (April 2008) Ino80 Chromatin Remodeling Complex Promotes Recovery of Stalled Replication Forks  Kenji Shimada, Yukako Oma, Thomas Schleker, Kazuto Kugou, Kunihiro Ohta, Masahiko Harata, Susan M.

Figure 1 Localization of the INO80 Complex on Yeast Chromosomes (A) ChIP-chip analysis was performed with anti-Arp5 (top) or anti-Myc antibody (bottom) on lysates from cell bearing Ino80-13myc as the only tagged locus. Random cultures of cells were crosslinked with formaldehyde and lysed for ChIP as described in the Experimental Procedures. Data from yeast Chr 3 are shown and data from other chromosomes (Chr4, Chr5, and Chr6R) are shown graphically in Figures S1–S3. Vertical bars represent the binding ratio of proteins in each locus. The loci, which cover 300 bp and 150 bp regions, are shown by yellow and black vertical bars, respectively. The scale of the vertical axis is the signal log ratio [49], and the horizontal axis shows kilobase units. Red arrows indicate the position of replication origins (ARS), and black arrows indicate tRNA genes. (B) ChIP-chip analysis was performed with anti-Myc mAb on lysates from cells bearing Ino80-13myc as the only tagged locus. Cells were arrested in G1 with α-factor for the first sample (top) and then synchronously released in 0.2 M HU for 60 min as the second sample (bottom). Data from the left arm of yeast Chr3 are shown. Arrows indicate the positions of replication origins (ARS). (C) ChIP-chip analysis for Ino80-13myc was performed in cells arrested in α-factor or in HU. The enrichment of Ino80-13myc in HU (vertical axis) is plotted against the enrichment on α-factor (horizontal axis) as red diamonds. The blue squares indicate Ino80-13myc signals at ARS. The scale of the axes is the log2 value of the hybridization signals [49]. The regression lines for all loci (lower line) and for all ARS loci (upper line) are shown.

Figure 2 The Increase in Ino80 near Origins on HU Parallels the Binding of Stalled Replication Polymerases (A) Cells bearing a genomic copy of Ino80-Avi tag and an isogenic nontagged strain, both carrying pRS415-NLS-BirA, were cultured with biotin to allow tagging of Ino80. These cells and cells bearing Pol2-13myc [48] were synchronized in G1 with α-factor and then released into 0.2 M HU. ChIP samples were taken after 0, 20, 40, and 60 min in 0.2 M HU and analyzed by real-time qPCR for ARS607 and for loci +4 kb and +14 kb from ARS607 [48]. We note that Ino80 levels in G1 are slightly higher at +4kb than at the origin, probably reflecting its binding to the promoter of the gene ATG18 found at this site (see map). The fold enrichment is plotted over a background control of TK gene (see the Experimental Procedures). Error bars represent the standard error of four PCR reactions. (B) Ino80 association at ARS elements and at the rDNA replication fork barrier increases in HU-blocked cells. Cells bearing a genomic copy of Ino80-13myc were cultured in α-factor (left panel) or were subsequently released into YPD medium containing 0.2 M HU for 60 min (middle). For G2/M-phase arrest, cells were cultured in 15 μg/ml nocodazole for 3 hr (right panel). ChIP samples obtained with Ino80-13myc were analyzed by qPCR for sequences at the following ARS elements (306, 606, 607, 608, and 609), at rDNA loci (rDNA ARS; NTS, nontranscribed region; RFB, replication fork barrier; and 35S, 35S rRNA gene), and at control loci (FAB1 and SAP155). In this panel, Ino80-13myc signal intensity is plotted as a fold enrichment over the signal at FAB1 (+14 kb from ARS607), which showed little or no variation on HU (see [A]). Error bars represent the standard error of three independent experiments. Current Biology 2008 18, 566-575DOI: (10.1016/j.cub.2008.03.049) Copyright © 2008 Elsevier Ltd Terms and Conditions

Figure 3 ino80 and arp8 Mutations Impair Resumption of Replication after HU Treatment (A) A wild-type strain (GA-2263) and isogenic disruptions for either ino80, arp5, or rad51 were arrested in α-factor then released into 0.2 M HU and held for 0, 2, 4, and 6 hr. Cells were then plated in triplicate onto rich media without HU (YPD) and colony formation was scored after 3 days at 30°C. Wild-type strain values are used for normalization (100%). Error bars represent the standard deviation of triplicates. (B) Wild-type, ino80, and arp8 cells were synchronously released into 0.2 M HU as in (A) for 90 min. Cells were then washed and released into fresh YPD, and samples were taken for FACS analysis. We could monitor a delay in progression from G1 into S phase in the absence of ino80 when an unperturbed cell cycle was monitored by FACS (data not shown). This is likely to reflect Ino80-dependent changes in G1 transcriptional events [4, 6] because early-origin firing is unaffected by the mutation (C). (C) Two-dimensional gel analysis was performed on the cell samples taken for FACS in (B) at the indicated time points. PstI digested genomic DNA was analyzed by 2D gels probed for ARS607 and a site at +8 kb from ARS607.

Figure 4 Recovery from Stalled Replication Forks Fails in ino80 Mutants (A) Isogenic wild-type and ino80 cells bearing Ddc2-GFP were synchronized in G1 and blocked in 0.2 M HU for 90 min and then released into fresh YPD for the indicated times. The frequency of cells having one, two, or greater than three Ddc2-foci are plotted. Images of typical signals are shown. The level of Ddc2-GFP foci in S-phase cells of an exponential culture are labeled “S-exp.” Over 100 cells are scored for each point. (B) Isogenic wild-type (GA-4956) and ino80 cells (GA-2264) expressing Rad52-YFP (pWJ1213, a gift form R. Rothstein) were cultured in SC-His. Cells were synchronously released into SC-His + 0.2M HU for 90 min and then were released into fresh SC-His for 2 hr. α-factor was added to the culture after 90 min to block the entry into next S phase. Frequency of cells having one, two, or greater than three Rad52-foci is plotted. (C) Isogenic wild-type, ino80, and arp8 cells bearing hENT1 and 8× TK were released synchronously into 0.2 M HU containing CldU for 1.5 hr. Cells were washed and released in fresh YPD containing IdU. After 45 min, cells were blocked prior to mitosis by nocodazole (15 μg/ml) and cultured for another 45 min. Genomic DNA was sonicated and denatured, and CldU and IdU incorporated DNA fragments were recovered by immunoprecipitation (see the Experimental Procedures for details). The distribution of label around origins was probed by real-time PCR for ARS607, ARS607+4k, ARS607+14k, and ARS522. The ratio of recovered IP/input DNA is normalized to that of ARS607.

Figure 5 Downregulation of Rad53 Phosphorylation Is Delayed during the Recovery from Fork Arrest in ino80 Cells Exponentially growing wild-type (GA-4956), ino80 (GA-2264), and arp5 (GA-2181) mutant cells were synchronized with α-factor in G1 and released into YPAD + 0.2 M HU. After 90 min cells were washed and released into fresh YPD for the indicated times. Rad53 mobility shift (Rad53∗) was monitored at the indicated time points. Rad53 was detected with anti-Rad53 antibody (yC-19, Santa Cruz). Current Biology 2008 18, 566-575DOI: (10.1016/j.cub.2008.03.049) Copyright © 2008 Elsevier Ltd Terms and Conditions
