Enhancers instruct spatio-temporally specific gene expression in a manner tightly linked to higher-order chromatin architecture. Critical chromatin architectural regulators condensin I and condensin II play non-redundant roles controlling mitotic chromosomes. But aspects of interphase condensin loading and function, or in transcription regulation remain unclear. Here we report that both condensin complexes exhibit an unexpected, dramatic estrogen-induced recruitment to estrogen receptor α (ER-α)-bound eRNA+ active enhancers in interphase breast cancer cells, exhibiting non-canonical interaction with ER-α via its DNA-binding domain (DBD). Condensins positively regulate ligand-dependent enhancer activation, at least in part, by recruiting an E3 ubiquitin ligase, HECTD1, to modulate the binding of enhancer-associated coactivators/corepressors, including p300 and RIP140, permitting full eRNA transcription, formation of enhancer:promoter looping and the resultant coding gene activation. Collectively, our results reveal an important, unanticipated transcriptional role of interphase condensins in modulating estrogen-regulated enhancer activation and coding gene transcriptional program.
