An ATM D-compartmentalization in DNA damage response

Trends Cell Biol. 2024 Mar;34(3):173-175. doi: 10.1016/j.tcb.2023.12.003. Epub 2023 Dec 29.

Abstract

How chromatin configuration impacts DNA repair is an emerging question. A recent study by Arnould et al. shows that ATM orchestrates a new chromatin compartment (D compartment) following DNA double-strand breaks and establishes that this compartment enhances cellular response to such breaks but also introduces a risk to genome integrity.

Keywords: ATM; D compartment; DNA damage response; DNA repair; chromatin compartmentalization; genome integrity.
