Ultra long-range genomic contacts, which emerge as prominent components of genome architecture, constitute a biochemical paradox. This is because regulatory DNA elements make selective and stable contacts with DNA sequences located megabases away, instead of interacting with proximal sequences occupied by the same exact transcription factors (TF). This is exemplified in olfactory sensory neurons (OSNs), where only a fraction of Lhx2/Ebf1/Ldb1-bound sites interact with each other, converging into highly selective multi-chromosomal enhancer hubs.
