摘要

Developments in proximity ligation methods and sequencing technologies have provided high-resolution views of the organization of the genome inside the nucleus. A prominent feature of Hi-C maps is regions of increased self-interaction called topologically associating domains (TADs). Despite the strong evolutionary conservation and clear link with gene expression, the exact role of TADs and even their definition remains debatable. Here, I review the discovery of TADs, how they are commonly identified, and the mechanisms that lead to their formation. Furthermore, I discuss recent results that have created a more nuanced view of the role of TADs in the regulation of genes. In light of this, I propose that when we define TADs, we also consider the mechanisms that shape them. (C) 2019 Elsevier Ltd. All rights reserved.
