Project description:UMI-4C for quantitative and targeted chromosomal contact profiling
| PRJNA308557 | ENA
Project description:We developed a targeted chromosome conformation capture (4C) approach that uses unique molecular identifiers (UMI) to derive high complexity quantitative chromosome contact profiles with controlled signal to noise ratios. We demonstrate that the method improves the sensitivity and specificity for detection of long-range chromosomal interactions, and that it allows the design of interaction screens with predictable statistical power. UMI-4C robustly quantifies contact intensity changes between cell types and conditions, opening the way toward incorporation of long-range interactions in quantitative models of gene regulation.

We demonstrate that the method improves the sensitivity and specificity for detection of long-range chromosomal interactions, and that it allows the design of interaction screens with predictable statistical power. UMI-4C robustly quantifies contact intensity changes between cell types and conditions, opening the way toward incorporation of long-range interactions in quantitative models of gene regulation. We constructed UMI-4C profiles of 13 different genomic loci (viewpoints) in five different cell lines, in order to study the 3D chromatin contact maps of these selected loci. The coordinates for these viewpoints are: G1p1 chrX:48646542; baitG1_3_5kb chrX:48641393; bait_50kb chrX:48595987; bait_165kb chrX:48476525; ANK1 chr8:41654693; hbb_3HS chr11:5221346; hbb_HBB chr11:5248714; hbb_HBBP1_G1 chr11:5266532; HBB_HBE chr11:5292159; HBB_HS2 chr11:5301345; HBB_HS3 chr11:5306690; HBB_HS5 chr11:5313539; HBB_HBD chr11:5256597

Project description:Animal genomes fold into contact domains defined by enhanced internal contact frequencies with debated functions in establishing independent gene regulatory domains. A large fraction of contact domains in mammals are formed by stalling of chromosomal loop-extruding cohesin by CTCF at domain boundaries. 90% of domain boundaries in Drosophila form CTCF-independently, and other proteins were proposed to form chromosomal loops with dual functions of segregating promoters from inappropriate regulatory elements and connecting distal regulatory elements to their correct targets. Here, we genetically ablate the ubiquitous boundary-associated factor Cp190 and assess impacts on genome folding and transcriptional regulation in embryos. Our results reveal that Cp190 is a major factor required for contact domain boundary formation and gene insulation in Drosophila.
