Poly(ADP-ribose): PARadigms and PARadoxes [PDF]
Poly(ADP-ribosyl)ation (PARylation) is a posttranslational protein modification (PTM) catalyzed by members of the poly(ADP-ribose) polymerase (PARP) enzyme family. PARPs use NAD(+) as substrate and upon cleaving off nicotinamide they transfer the ADP-ribosyl moiety covalently to suitable acceptor proteins and elongate the chain by adding further ADP ...

PARP (Poly ADP‐ribose Polymerase) Family in Health and Disease [PDF]
The poly(ADP‐ribose) polymerase (PARP) family consists of 17 members of nicotinamide adenine dinucleotide (NAD⁺)‐dependent enzymes that regulate key biological processes by catalyzing adenosine diphosphate (ADP)‐ribosylation, either poly(ADP‐ribosyl ...

PARG Mutation Uncovers Critical Structural Determinant for Poly(ADP-Ribose) Hydrolysis and Chromatin Regulation in Embryonic Stem Cells [PDF]
Poly(ADP-ribosyl)ation is a crucial posttranslational modification that governs gene expression, chromatin remodeling, and cellular homeostasis. This dynamic process is mediated by the opposing activities of poly(ADP-ribose) polymerases (PARPs), which ...

Selective monitoring of the protein-free ADP-ribose released by ADP-ribosylation reversal enzymes.
ADP-ribosylation is a key post-translational modification that regulates a wide variety of cellular stress responses. The ADP-ribosylation cycle is maintained by writers and erasers.

Poly ADP-ribose polymerases (PARPs) catalyze ADP-ribosylation, a subclass of post-translational modification (PTM). Mono-ADP-ribose (MAR) moieties bind to target molecules such as proteins and nucleic acids, and are added as part of the process which ...

Protein poly(ADP-ribosyl)ation regulates arabidopsis immune gene expression and defense responses. [PDF]
Perception of microbe-associated molecular patterns (MAMPs) elicits transcriptional reprogramming in hosts and activates defense to pathogen attacks. The molecular mechanisms underlying plant pattern-triggered immunity remain elusive.

Determination of ADP‐ribose and Poly(ADP‐ribose) by a New Radioimmunoassay [PDF]
A specific and sensitive radioimmunoassay for ADP‐ribose has been developed on the basis of the selective conversion of ADP‐ribose to 5′‐AMP by alkaline treatment. Antibodies highly specific against 5′‐AMP allowed quantification of ADP‐ribose converted to 5′‐AMP in the range of 1–40 pmol, and in the presence of large quantities of nucleic acids or 3 ...

Chromatin composition is changed by poly(ADP-ribosyl)ation during chromatin immunoprecipitation. [PDF]
Chromatin-immunoprecipitation (ChIP) employs generally a mild formaldehyde cross-linking step, which is followed by isolation of specific protein-DNA complexes and subsequent PCR testing, to analyze DNA-protein interactions.

Cas9 is mostly orthogonal to human systems of DNA break sensing and repair.
CRISPR/Cas9 system is а powerful gene editing tool based on the RNA-guided cleavage of target DNA. The Cas9 activity can be modulated by proteins involved in DNA damage signalling and repair due to their interaction with double- and single-strand breaks (
