Web21 Mar 2024 · HPF1 and nucleosomes mediate a dramatic switch in activity of PARP1 from polymerase to hydrolase. HPF1 dynamically controls the PARP1/2 balance between … Weba reaction known as PARylation. Primary targets of PARP1/ PARP2 activities are histones, the protein components of nucleo-somes that structure the genome in all eukaryotes to form chroma-tin. PARylation of histones is mediated by histone PARylation factor 1 (HPF1), which contributes to a shared active site with PARP1/PARP2 [5–10].
