The other X chromosome (without the pluripotency factors and CTCF proteins) turns off Tsix expression and begins to express the Xist RNA. As a result, the X chromosome that expresses Xist will be …

WebIn addition to rich maps of chromatin protein occupancy from 50 cells, we were able to map the genome-wide binding sites of CTCF and two pluripotency TFs, SOX2 and NANOG, in single cells. Because each individual TF binding site is present in only 2–4 copies per diploid cell, single-cell TF profiling is a considerable technical challenge. WebMay 12, 2011 · CTCF-independent RAD21 binding sites preferentially co-localize with key pluripotency related transcription factors. Despite the high overlap of RAD21 and CTCF binding, we also identified 4087 (26.7%) RAD21 binding sites that did not co-localize with CTCF in ESCs (Fig. 1A and Table S2).
