Molecular basis of CTCF binding polarity in genome folding

Molecular basis of CTCF binding polarity in genome folding

The boundaries of topologically associating domains (TADs) arise from the ability of the CTCF protein to stop extrusion of chromatin loops by cohesin. Here the authors find that CTCF positions cohesin through its N-terminus but does not control its overall binding dynamics on chromatin, and show how...

Description
Résumé:The boundaries of topologically associating domains (TADs) arise from the ability of the CTCF protein to stop extrusion of chromatin loops by cohesin. Here the authors find that CTCF positions cohesin through its N-terminus but does not control its overall binding dynamics on chromatin, and show how the orientation of CTCF binding sites translates into genome folding patterns.
