PARP enzymes are essential in a number of cellular functions, [6] including expression of inflammatory genes: [7] PARP1 is required for the induction of ICAM-1 gene expression by cardiac myocytes [8] and smooth muscle cells, in response to TNF.

PARP is a critical enzyme involved in DNA repair and many other cellular processes including transcription and modulation of chromatin structure. PARP plays a central role in NER and BER, and enables repair of DNA damage caused by alkylating agents and chemotherapeutic drugs.

Poly [ADP-ribose] polymerase 1 (PARP-1) also known as NAD+ ADP-ribosyltransferase 1 or poly [ADP-ribose] synthase 1 is an enzyme that in humans is encoded by the PARP1 gene. [5] It is the most abundant of the PARP family of enzymes, accounting for 90% of …

A diverse collection of domain structures dictates the different cellular roles of PARP enzymes and regulates the production of poly (ADP-ribose). Here we primarily review recent structural insights into the regulation and catalysis of two family members: PARP-1 and Tankyrase.

Poly (ADP-ribose) polymerase 1 (PARP-1), newly termed ADP-ribosyltransferase D-type 1 (ARTD1), is a ubiquitously expressed ADP-ribosyltransferase (ART) enzyme involved in key cellular processes such as DNA repair and cell death.

Poly (ADP-ribose) polymerases (PARP) 1-3 are well-known multi-domain enzymes, catalysing the covalent modification of proteins, DNA, and themselves. They attach mono- or poly-ADP-ribose to targets using NAD+ as a substrate.

2011年10月11日 · PARP-1 has a key role in the repair of single-strand breaks (SSBs), resulting from oxidative stress via the base excision repair/SSB repair (BER/SSBR) pathway.

2005年5月1日 · Poly (ADP-ribose) polymerase (PARP) is a family of enzymes present in eukaryotes, which catalyses poly (ADP-ribosyl)ation of DNA-binding proteins (Udea, 1990; Lautier et al., 1993; Lindahl et al., 1995; D’Amours et al., 1999).

Poly (ADP-ribose) polymerase (PARP) is a class of nuclear enzymes responsible for DNA damage detection and repair, favoring the maintenance of genomic stability and the regulation of metabolic or signal transduction processes in health and disease.

2023年4月28日 · PARPs catalyze ADP-ribosylation—a post-translational modification that plays crucial roles in biological processes, including DNA repair, transcription, immune regulation, and condensate formation. ADP-ribosylation can be added to a wide range of amino acids with varying lengths and chemical structures, making it a complex and diverse modification.
