SRP074187 PRJNA320088 GSE80824 Identification of in vivo binding sites for YY2. We report the application of next generation sequencing for high-throughput profiling of Yin Yang 2 (YY2) binding sites in mammalian Trophectoderm Stem cells. Sequencing of chromatin obtained in chromatin-immunoprecipitation (ChIP) assays carried out with aYY2 serum yielded over ten million sequence reads. Peak finding allowed us allowed us to identify a limited number of chromatin targets for YY2. Putative binding sites were validated in regular ChIP assays and gene expression of a few genes nearby was altered in the absence of Yy2. This study provides a framework to understand the role of YY2 in diverse mammalian cell populations. Overall design: Examination of YY2 binding sites in TSB7 cells. GSE80824
