  1. ...Calling Cards enable multiplexed identification of the genomic targets of DNA-binding proteins Haoyi Wang 1 , 3 , 4 , David Mayhew 1 , 3 , Xuhua Chen 1 , Mark Johnston 2 , 5 and Robi David Mitra 1 , 5 1 Department...
  2. ..., hinging on the precise binding of transcription factors (TFs) and cofactors to gene regulatory elements such as promoters and enhancers. Although it is relatively routine to profile -wide DNA binding landscapes of proteins, identifying the specific proteins that bind to, and regulate the transcription of...

  3. ...the largest and most enigmatic class of human transcription factors. Their C2H2-ZF arrays are highly variable, indicating that most will have unique DNA binding motifs. However, most of the binding motifs have not been directly determined. In addition, little is known about whether or how these proteins...
  4. ...the protocol “High Molecular Weight DNA (HMW DNA) Extraction from Cells” (NEB T3050) with the following alterations: (1) the agitation speed during cell lysis was set to 1400 rpm for 10 min; (2) the incubation time with beads during gDNA binding to beads was increased to 8 min; (3) the elution buffer...
  5. ...cards. One such technology is DamID, in which a DNA-methyltransferase is tethered to a DNA-binding protein and changes in DNA methylation relative to a control are assayed to determine binding location (van Steensel and Henikoff 2000; Hass et al. 2015; Tosti et al. 2018). Another is CUT&RUN, in which...
  6. ...higher normalized number of super-enhancers than the non-HIMs across cell types (Fig. 3C; Supplemental Fig. S12). This significant pattern is consistent with varied window sizes from 20 kb to 1 Mb (Supplemental Fig. S12).Protein–protein interactions (PPIs) can further stabilize TF-DNA binding...
  7. ...-specific gains and losses within snakes (Fig. 1A; Table 1; Supplemental Table S3; Supplemental Methods). We identified 45% more genes than previous reconstructions: a total of 1648 genes in 1300 protein-coding gene families on the ancestral autosomes that became the caenophidian Z and W sex chromosomes (Fig. 1B...
  8. ....Identification and quantification of REsWe define regulatory elements (REs) by the union of open peaks from ATAC-seq (called by MACS2) data on each time point. In the whole induction process, we get 174,059 REs in total. To quantify the accessibility of the peaks, we calculate the openness score for each sample in each region...
  9. ...budgets. Although great strides have been made in in vivo binding analysis using methods such as ChIP-seq ( Johnson et al. 2007; Landt et al. 2012), Bio-ChIP (vanWervenandTimmers 2006), or Calling Cards (Wang et al. 2012), these are challenging experiments that are not easily scaled to many TFs outside...
  10. ...C was 68% for DNA and 69%/73% for protein. The ST131 espC island has genes coding for fimD, focC ( fimC), tsh, cfaD (regA), and espC, alongwith two poorly characterized proteins, one with similarity to fimbrial adhesins and one to DNA Figure 2. Proportions of STs during the 11-yr sampling framework...
