A Long-Distance Chromatin Affair
Changes in transcription factor binding sequences result in correlated changes in chromatin composition locally and at sites hundreds of kilobases away. New studies demonstrate that this concordance is mediated via spatial chromatin interactions that constitute regulatory modules of the human genome.
متن کاملA complex affair
Tight junctions (TJs) are protein complexes comprised of claudins, which anchor them in the membrane and numerous cytosolic scaffolding proteins including MAGI, MUPP1, cingulin and members of the Zonula Occludens (ZO) family. Originally, their main function was thought to be as a paracellular barrier. More recently, however, additional roles in signal transduction, differentiation and prolifera...
متن کاملMetabolic remodeling: a pyruvate transport affair.
Metabolic remodeling is a major determinant for many cell fate decisions, and a switch from respiration to aerobic glycolysis is generally considered as a hallmark of cancer cell transformation. Pyruvate is a key metabolite at the major junction of carbohydrate metabolism between cytosolic glycolysis and the mitochondrial Krebs cycle. In this issue of The EMBO Journal, Bender et al show that ye...
متن کاملChromatin remodeling complex NURF regulates thymocyte maturation.
The maturation of T cells requires signaling from both cytokine and T-cell receptors to gene targets in chromatin, but how chromatin architecture influences this process is largely unknown. Here we show that thymocyte maturation post-positive selection is dependent on the nucleosome remodeling factor (NURF). Depletion of Bptf (bromodomain PHD finger transcription factor), the largest NURF subun...
متن کاملMurine esBAF chromatin remodeling complex subunits BAF250a
Background: Cellular differentiation and reprogramming are accompanied by changes in replication timing and 3D organization of large-scale (400 to 800 Kb) chromosomal domains (‘replication domains’), but few gene products have been identified whose disruption affects these properties. Results: Here we show that deletion of esBAF chromatin-remodeling complex components BAF250a and Brg1, but not ...
