Regulation of cohesin-mediated chromosome structure by PDS5 in mammals [ChIP-seq]

Project description:Cohesin regulates sister chromatids cohesion but also contributes to chromosome folding by promoting the formation of chromatin loops, a process proposed to be mediated by loop extrusion. PDS5 plays a crucial role in regulating the cohesin dynamic on chromatin, mainly through WAPL-mediated release activity and the opponent ESCO1/2-sororin dependent pathway. However, the exact function of PDS5 on cohesin-mediated chromatin looping remains ambiguous. Two versions of PDS5 exist in vertebrates, PDS5A and PDS5B. Here, we construct cells for rapid PDS5A or PDS5B degradation in PLC/PRF/5 cell line with the FKBP12F36V-dTAG degron system to perform loss of function studies. Combining Hi-C, ChIP-seq for cohesin regulators, and RNA-seq data, we describe the redundant and discrete roles of PDS5A and PDS5B in three-dimensional genome organization and gene expression.
