Folding makes an imprint.
Genes Dev. 37, 779-780 (2023)
Imprinted gene clusters are confined genomic regions containing genes with parent-of-origin-dependent transcriptional activity. In this issue of Genes & Development, Loftus and colleagues (pp. 829-843) made use of an insightful combination of descriptive approaches, genetic manipulations, and epigenome-editing approaches to show that differences in nuclear topology precede the onset of imprinted expression at the Peg13-Kcnk9 locus. Furthermore, the investigators provide data in line with a model suggesting that parent-of-origin-specific topological differences could be responsible for parent-of-origin-specific enhancer activity and thus imprinted expression.
