Trex2 responds to damaged replication forks in diverse ways

Mol Cell Oncol. 2021 Feb 25;8(2):1881394. doi: 10.1080/23723556.2021.1881394. eCollection 2021.

Abstract

Three prime Repair Exonuclease 2 (Trex2) alters replication fork (RF) stability and mutation levels in cells defective for homologous recombination (HR). Trex2 has multiple functions that can either cause or supress RF instability in cells with different HR-defects. Why does Trex2 have such diverse effects on RF maintenance?
