Supplementary information

PARP2 also known as Poly (ADP-ribose) polymerase 2 plays an important role in the repair of damaged DNA. This protein has a molecular mass of approximately 62 kDa. Researchers usually find PARP2 expression in the nucleus primarily in cells undergoing stress or damage responses. The PARP2 protein interacts with substrates during the DNA repair process facilitating the attachment of ADP-ribose polymers to target proteins which is a critical step in the cellular response to DNA strand breaks.
Biological function summary

Poly (ADP-ribose) polymerase 2 serves a critical function in maintaining genomic stability. This protein is part of the PARP protein family and operates in conjunction with PARP1. Together they form a complex that senses DNA damage and initiates the repair mechanism. This action helps prevent mutations and genome rearrangements which could otherwise lead to cell death or oncogenesis.

Pathways

PARP2 contributes significantly to the base excision repair (BER) and homologous recombination (HR) pathways. It collaborates with other repair enzymes and kinases like XRCC1 and DNA-PKcs to effectively mediate the repair processes. The activity of PARP2 ensures prompt and accurate repair of single-strand and double-strand DNA breaks allowing these pathways to maintain cellular homeostasis and integrity.

PARP2 associates prominently with cancer and neurodegenerative diseases. Due to its DNA repair function improper regulation or expression of PARP2 may lead to an increased risk of tumorigenesis making it a target for cancer therapy. Additionally disorders like Alzheimer's disease show an association with PARP2 due to its relationship with oxidative stress and DNA damage. Therapies targeting PARP2 along with PARP1 represent a promising approach in treating these conditions by enhancing DNA repair or inducing synthetic lethality in cancer cells.

General info

Function

Poly-ADP-ribosyltransferase that mediates poly-ADP-ribosylation of proteins and plays a key role in DNA repair (PubMed : 10364231, PubMed : 25043379, PubMed : 27471034, PubMed : 30104678, PubMed : 32028527, PubMed : 32939087, PubMed : 34108479, PubMed : 34486521, PubMed : 34874266). Mediates glutamate, aspartate or serine ADP-ribosylation of proteins : the ADP-D-ribosyl group of NAD(+) is transferred to the acceptor carboxyl group of target residues and further ADP-ribosyl groups are transferred to the 2'-position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units (PubMed : 25043379, PubMed : 30104678, PubMed : 30321391). Serine ADP-ribosylation of proteins constitutes the primary form of ADP-ribosylation of proteins in response to DNA damage (PubMed : 32939087). Mediates glutamate and aspartate ADP-ribosylation of target proteins in absence of HPF1 (PubMed : 25043379). Following interaction with HPF1, catalyzes serine ADP-ribosylation of target proteins; HPF1 conferring serine specificity by completing the PARP2 active site (PubMed : 28190768, PubMed : 32028527, PubMed : 34108479, PubMed : 34486521, PubMed : 34874266). PARP2 initiates the repair of double-strand DNA breaks : recognizes and binds DNA breaks within chromatin and recruits HPF1, licensing serine ADP-ribosylation of target proteins, such as histones, thereby promoting decompaction of chromatin and the recruitment of repair factors leading to the reparation of DNA strand breaks (PubMed : 10364231, PubMed : 32939087, PubMed : 34108479). HPF1 initiates serine ADP-ribosylation but restricts the polymerase activity of PARP2 in order to limit the length of poly-ADP-ribose chains (PubMed : 34732825, PubMed : 34795260). Specifically mediates formation of branched poly-ADP-ribosylation (PubMed : 30104678). Branched poly-ADP-ribose chains are specifically recognized by some factors, such as APLF (PubMed : 30104678). In addition to proteins, also able to ADP-ribosylate DNA : preferentially acts on 5'-terminal phosphates at DNA strand breaks termini in nicked duplex (PubMed : 27471034, PubMed : 29361132).

Sequence similarities

Belongs to the ARTD/PARP family.

Post-translational modifications

Auto poly-ADP-ribosylated on serine residues, leading to dissociation of the PARP2-HPF1 complex from chromatin (PubMed:32939087, PubMed:34108479). Poly-ADP-ribosylated by PARP1 (By similarity).. Acetylation reduces DNA binding and enzymatic activity.. Proteolytically cleaved by caspase-8 (CASP8) in response to apoptosis, leading to its inactivation.
