Project description:We used SLAM-seq approach to define a contribution of RNA synthesis into RNA abundance changes after Tpr loss. Basket nucleoporin Tpr was AID-tagged and depleted through Auxin Induced Degradation system. Loss of Tpr led to rapid changes in rates of RNA synthesis. The majority of transcripts were downregulated. Analysis of RNA-seq and SLAM-seq indicated that the changes in RNA abundance of most of Tpr-dependent up- and downregulated genes resulted from increased or decreased rates of RNA synthesis, respectively.

Project description:Gene expression is orchestrated by transcription factors (TFs), which bind to DNA in a sequence-specific manner, and by spatial genome structure, which constrains and shapes TF activity. Zinc finger protein 143 (ZNF143/ZFP143) is a TF that has been implicated in both gene activation and 3D genome organisation. We have generated an acute ZNF143/ZFP143 depletion system to study its direct consequences on chromatin looping and gene transcription. The effects of ZNF143/ZFP143 depletion are inconsistent with it being a looping factor, which we further confirmed by systematic analysis of previous studies. However, degradation of ZNF143/ZFP143 led to the down-regulation of hundreds of its targets, which were found to be enriched in nuclear-encoded mitochondrial genes. By studying the consequences of ZNF143/ZFP143 loss in monoculture and in an in vitro embryonic development model, we establish ZNF143/ZFP143 as a conserved transcriptional regulator of cell proliferation and differentiation by modulating mitochondrial functions.

Project description:The transcription factor ZNF143 contains seven tandem zinc fingers and is involved in 3D genome construction; however, the mechanism by which ZNF143 functions in chromatin looping remains unclear. Here, we show that ZNF143 directionally recognizes diverse genomic sites and is required for chromatin looping between these sites. In addition, ZNF143 is located between CTCF and cohesin at numerous CTCF sites and ZNF143 removal narrows the space between CTCF and cohesin. Moreover, genetic deletion of ZNF143, in conjunction with acute CTCF depletion, revealed that ZNF143 and CTCF collaborate to regulate higher-order genome organization. Thus, ZNF143 is recruited by CTCF to the CTCF sites to regulate TAD formation and genome compartmentalization whereas directional recognition of DNA motifs directly by ZNF143 itself regulates promoter activity via chromatin looping.
