DNA damage induces transcriptional repression of E2F1 target genes and a reduction in histone H3-Thr11 phosphorylation (H3-pThr11 ) at E2F1 target gene promoters. Dephosphorylation of H3-pThr11 is partly mediated by Chk1 kinase and protein phosphatase 1γ (PP1γ) phosphatase. Here, we isolated NIPP1 as a regulator of PP1γ-mediated H3-pThr11 by surveying nearly 200 PP1 interactor proteins. We found that NIPP1 inhibits PP1γ-mediated dephosphorylation of H3-pThr11 both in vivo and in vitro. By generating NIPP1-depleted cells, we showed that
