"We find that while TAD boundaries pair more frequently than non-boundary regions, these interactions are infrequent and are uncorrelated with transcriptional activity of genes within the TAD. (...) These results suggest that TAD boundary architecture and gene activity are largely uncoupled"

TAD boundary architecture and gene activity are uncoupled
Topologically associating domains (TADs) are prominent features of genome organization. A proposed function of TADs is to contribute to gene regulation by promoting chromatin interactions within a TAD...
