Abstract

BRCA2, the breast cancer susceptibility gene factor, interacts with TREX-2, a protein complex involved in the biogenesis and export of messenger ribonucleoprotein, to process DNA–RNA hybrid structures called R-loops that can trigger genome instability; these may be a central cause of the stress occurring in early cancer cells that drives oncogenesis.
