Abstract

The Caenorhabditis elegans Integrator complex is a set of at least 13 evolutionarily conserved proteins that binds the C-terminal domain of RNA polymerase II to regulate snRNA 3'-end processing and gene expression. Here we show that the Integrator subunit 6 intervenes in the DNA damage response in C. elegans . We find that upon X-ray radiation, INTS-6 is necessary for RAD-51 foci formation. In addition, CDK-1 Tyr-15 phosphorylation depends on the presence of INTS-6 . This work adds a new piece to elucidate the Integrator complex mechanism of action in DNA repair.
