Activity Assays for Poly-ADP Ribose Polymerase
2004Poly(ADP-ribose) polymerase (PARP-1) is a nuclear enzyme that has traditionally been thought to require discontinuous or "damaged" DNA (dcDNA) as a coenzyme, a preconception that has limited research mainly to its role in cell pathology, i.e., DNA repair and apoptosis.

Regulatory mechanisms of poly(ADP-ribose) polymerase
Molecular and Cellular Biochemistry, 1999Here, we describe the latest developments on the mechanistic characterization of poly(ADP-ribose) polymerase (PARP) [EC 2.4.2.30], a DNA-dependent enzyme that catalyzes the synthesis of protein-bound ADP-ribose polymers in eucaryotic chromatin. A detailed kinetic analysis of the automodification reaction of PARP in the presence of nicked dsDNA ...

Interaction of poly(ADP-ribose)polymerase with DNA polymerase ?
Molecular and Cellular Biochemistry, 1994Homogeneously purified poly(ADP-ribose) polymerase (PARP) specifically stimulated the activity of immunoaffinity-purified calf or human DNA polymerase alpha by about 6 to 60-fold. Apparently, poly(ADP-ribosyl)ation of DNA polymerase alpha was not necessary for the stimulation.

Inhibition of poly(ADP-ribose) polymerase in cancer
Current Opinion in Pharmacology, 2006Inhibition of the DNA repair enzyme poly(ADP-ribose) polymerase-1 (PARP-1) has been extensively investigated in the pre-clinical setting as a strategy for chemo- or radio-potentiation. Recent evidence has suggested that PARP inhibitors might be active as single agents in certain rare inherited cancers that carry DNA repair defects.

Poly(ADP-ribose) polymerase catalyses the formation of ADP-ribose polymers covalently attached to various nuclear proteins, using NAD+ as substrate. The activity of this enzyme is strongly stimulated upon binding to DNA single or double strand breaks. Poly(ADP-ribosyl)ation is an immediate cellular response to DNA damage and is thought to be involved ...

Poly (ADP-ribose) polymerase 1
2022Poly (ADP-ribose) polymerase 1 is a key player in DNA repair and transcription regulation. The role of PARP1 in DNA damage recognition and protein signaling in response make it integral to genome stability. Beyond this, it regulates gene expression through chromatin remodeling and transcription factor binding.

Poly(ADP‐ribose) polymerase and poly(ADP‐ribose) glycohydrolase have been detected in chromatin extracts from the dinoflagellate Crypthecodinium cohnii. Poly(ADP‐ribose) glycohydrolase was detected by the liberation of ADP‐ribose from poly(ADP‐ribose).

Poly(ADP-ribose) polymerase and poly(ADP-ribose) glycohydrolase activities were both investigated in chicken erythroblasts transformed by Avian Erythroblastosis Virus. Respectively 21% and 58% of these activities were found to be present in the post-mitochondrial supernatant (PMS).

Poly(ADP‐ribose) polymerase: Molecular biological aspects
BioEssays, 1991AbstractA number of roles have been ascribed to poly(ADP‐ribose) polymerase* including involvement in DNA repair, cell proliferation, differentiation and transformation. Cloning of the gene has allowed the development of molecular biological approaches to elucidate the structure and the function(s) of this highly conserved enzyme.
