Poly(ADP-ribosyl)ation of p53 In Vitro and In Vivo Modulates Binding to its DNA Consensus Sequence
Neoplasia: An International Journal for Oncology Research, 2001 The tumor-suppresser p53 undergoes extensive poly(ADP-ribosyl)ation early during apoptosis in human osteosarcoma cells, and degradation of poly(ADP-ribose) (PAR) attached to p53 coincides with poly(ADP-ribose)polymerase-1, (PARP-1) cleavage, and ...

New readers and interpretations of poly(ADP-ribosyl)ation [PDF]
Trends in Biochemical Sciences, 2012 Poly(ADP-ribosyl)ation (PARylation), a protein post-translational modification that was originally connected to the DNA damage response, is now known to engage in a continuously increasing number of biological processes. Despite extensive research and ceaseless, important findings about its role and mode of action, poly(ADP-ribose) remains an enigma ...

Neoplasia: An International Journal for Oncology Research, 2014 Poly(ADP-ribose) polymerase-1 (PARP1) catalyzes the poly(ADP-ribosyl)ation of protein acceptors using NAD+ as the substrate is now considered as an important target for development of anticancer therapy. PARP1 is known to be post-translationally modified

PARP (Poly ADP‐ribose Polymerase) Family in Health and Disease
MedCommThe 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 ...

Poly(ADP-ribosyl)ation is recognized by ECT2 during mitosis [PDF]
Cell Cycle, 2014 Poly(ADP-ribosyl)ation is an unique posttranslational modification and required for spindle assembly and function during mitosis. However, the molecular mechanism of poly(ADP-ribose) (PAR) in mitosis remains elusive. Here, we show the evidence that PAR is recognized by ECT2, a key guanine nucleotide exchange factor in mitosis.

Poly(ADP-ribosyl)ation in mammalian ageing [PDF]
Nucleic Acids Research, 2007 Poly(ADP-ribose) polymerases (PARPs) catalyze the post-translational modification of proteins with poly(ADP-ribose). Two PARP isoforms, PARP-1 and PARP-2, display catalytic activity by contact with DNA-strand breaks and are involved in DNA base-excision repair and other repair pathways.

Poly(ADP-ribosyl)ation acts in the DNA demethylation of mouse primordial germ cells also with DNA damage-independent roles. [PDF]
PLoS ONE, 2012 Poly(ADP-ribosyl)ation regulates chromatin structure and transcription driving epigenetic events. In particular, Parp1 is able to directly influence DNA methylation patterns controlling transcription and activity of Dnmt1.

Chromatin composition is changed by poly(ADP-ribosyl)ation during chromatin immunoprecipitation. [PDF]
PLoS ONE, 2012 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.
