HPF1 remodels the active site of PARP1 to enable the serine ADP-ribosylation of histones
Once DNA breaks occur, poly(ADP-ribose) polymerase 1 (PARP1) ADP-ribosylates itself and other DNA repair factors to initiate the repair process. Here, the authors resolve the crystal structures of mouse and human HPF1, and human HPF1/PARP1 complex ...

The potential role and application of PARP inhibitors in cancer treatment [PDF]
Background: Since many anti-cancer agents act by inflicting DNA damage on tumour cells, there is increasing interest in the use of inhibitors of DNA repair to increase the cytotoxicity of these agents.

Increased DNA damage and the propension to cancer development, depend on the modulation of the mechanisms to control and maintain genomic integrity. Poly(ADP-Ribose)Polymerase activation and automodification are early responses to genotoxic stress.

Mcl-1 suppresses abasic site repair following bile acid–induced hepatic cellular DNA damage
In cholestasis, increases in bile acid levels result in the generation of reactive oxygen species and the induction of DNA damage and mutation. It is believed that bile acid accumulation is associated with liver tumorigenesis. However, the mechanism that

Structure, function and inhibition of poly(ADP-ribose)polymerase, member 14 (PARP14) [PDF]
Poly(ADP-ribose)polymerase, member 14 (PARP14, alternatively named ARTD8, BAL2, and COAST6) is an intracellular mono(ADP-ribosyl) transferase. PARP14 transfers a negatively charged ADP-ribose unit from a donor NAD+ molecule onto a target protein, post ...

Poly(ADP-Ribose) Polymerase 1: Cellular Pluripotency, Reprogramming, and Tumorogenesis [PDF]
Poly(ADP-ribos)ylation (PARylation) is the catalytic function of the Poly(ADP-ribose) polymerases (Parps) family for post-translational modification in cellular process. Being a major member of Parps, Parp1 is a crucial nuclear factor with biological significance in modulating DNA repair, DNA replication, transcription, DNA methylation and chromatin ...

Pyridazine Based Compounds with PARP-1 Inhibitory Activity
Pyridazine-containing compounds have been identified as potent PARP1 inhibitors. The PARP is a family of enzymes essential for many cellular processes such as DNA repair, genomic stability, and apoptosis, also known as poly(ADP-ribose) synthetases and ...

The XRCC1 phosphate-binding pocket binds poly (ADP-ribose) and is required for XRCC1 function [PDF]
Poly (ADP-ribose) is synthesized at DNA single-strand breaks and can promote the recruitment of the scaffold protein, XRCC1. However, the mechanism and importance of this process has been challenged.
