Intrinsically disordered proteins can phase separate from the soluble intracellular space, and tend to aggregate under pathological conditions. The physiological functions and molecular triggers of liquid demixing by phase separation are not well understood. Here we show in vitro and in vivo that the nucleic acid-mimicking biopolymer poly(ADP-ribose) (PAR)(More)
Post-translational modifications (PTMs) regulate many aspects of protein function and are indispensable for the spatio-temporal regulation of cellular processes. The proteome-wide identification of PTM targets has made significant progress in recent years, as has the characterization of their writers, readers, modifiers and erasers. One of the most elusive(More)
Harmful oxidation of proteins, lipids and nucleic acids is observed when reactive oxygen species (ROS) are produced excessively and/or the antioxidant capacity is reduced, causing 'oxidative stress'. Nuclear poly-ADP-ribose (PAR) formation is thought to be induced in response to oxidative DNA damage and to promote cell death under sustained oxidative stress(More)
