The eukaryotic genome is three-dimensionally segregated into discrete globules of topologically associating domains (TADs), within which numerous cis-regulatory elements such as enhancers and promoters interact to regulate gene expression. In this study, we identify a T-cell-specific sub-TAD containing the Gata3 locus, and reveal a previously uncharacterized long noncoding RNA (Dreg1) within a distant enhancer lying approximately 280 kb downstream of Gata3. Dreg1 expression is highly correlated with that of Gata3 during early immune system development and T helper type 2 cell differentiation. Inhibition and overexpression of Dreg1 suggest that it may be involved in the establishment, but not..
