Verification Image

Western blot analysis was performed on protein extracts (25 μg) from HepG2 (lane 2), SH-SY5Y (lane 3), HeLa (lane 4), MCF-7 (lane 5), HT-1080 (lane 6), and 293T (lane 7) using PARP2 antibody. Proteins were transferred onto a 0.45 μm PVDF membrane using the Trans-Blot^® Turbo^™ system for 13 min. The membrane was then blocked with 5% nonfat milk in TBST (HY-K1025) for 1 h at room temperature. Thhe primary antibody (1:1000) and loading control antibody GAPDH Antibody (HRP) (HY-P80954A) (1:2500) were diluted in 5% nonfat milk in TBST and incubated with the membrane overnight at 4°C. After washing, the membrane of primary antibody was incubated with HRP-conjugated goat anti-rabbit IgG (H&L) secondary antibody (HY-P8001) (1:5000) diluted in 5% nonfat milk in TBST for 1 h at room temperature. Protein bands were visualized using an Ultra High Sensitivity ECL detection kit (HY-K1005).

Background

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)

Subcellular Localization：Nucleus,Chromosome

Expression：
Tissue_Specificity: Widely expressed, mainly in actively dividing tissues (PubMed:10364231). The highest levels are in the brain, heart, pancreas, skeletal muscle and testis; also detected in kidney, liver, lung, placenta, ovary and spleen; levels are low in leukocytes, colon, small intestine, prostate and thymus (PubMed:10364231)

Isoforms & Post-Translational Modification：Q9UGN5 has two isomers: Q9UGN5-1: 66206 Da (predicted); Q9UGN5-2: 64805 Da (predicted).
Auto poly-ADP-ribosylated on serine residues, leading to dissociation of the PARP2-HPF1 complex from chromatin (PubMed:32939087, PubMed:34108479)丨Acetylation reduces DNA binding and enzymatic activity丨Proteolytically cleaved by caspase-8 (CASP8) in response to apoptosis, leading to its inactivation
