SRF promotes long-range chromatin loop formation and stem cell pluripotency.
Serum response factor (SRF) is a transcription factor essential for cell proliferation, differentiation, and migration and is required for primitive streak and mesoderm formation in the embryo. The canonical roles of SRF are mediated by a diverse set of context-dependent cofactors. Here, we show that SRF physically interacts with CTCF and cohesin subunits at topologically associating domain (TAD) boundaries and loop anchors. SRF promotes long-range chromatin loop formation and contributes to TAD insulation. In embryonic stem cells (ESCs), SRF associates with SOX2 and NANOG and contributes to the formation of three-dimensional (3D) pluripotency hubs. Our findings reveal additional roles of SRF in higher-order chromatin organization.
期刊介绍：
Cell Reports publishes high-quality research across the life sciences and focuses on new biological insight as its primary criterion for publication. The journal offers three primary article types: Reports, which are shorter single-point articles, research articles, which are longer and provide deeper mechanistic insights, and resources, which highlight significant technical advances or major informational datasets that contribute to biological advances. Reviews covering recent literature in emerging and active fields are also accepted.
The Cell Reports Portfolio includes gold open-access journals that cover life, medical, and physical sciences, and its mission is to make cutting-edge research and methodologies available to a wide readership.
The journal's professional in-house editors work closely with authors, reviewers, and the scientific advisory board, which consists of current and future leaders in their respective fields. The advisory board guides the scope, content, and quality of the journal, but editorial decisions are independently made by the in-house scientific editors of Cell Reports.
