Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Poly-ADP-ribosyltransferase that mediates poly-ADP-ribosylation of proteins and plays a key role in DNA repair. 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. Serine ADP-ribosylation of proteins constitutes the primary form of ADP-ribosylation of proteins in response to DNA damage. Mediates glutamate and aspartate ADP-ribosylation of target proteins in absence of HPF1. Following interaction with HPF1, catalyzes serine ADP-ribosylation of target proteins; HPF1 conferring serine specificity by completing the PARP2 active site. 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. In addition to proteins, also able to ADP-ribosylate DNA: preferentially acts on 5'-terminal phosphates at DNA strand breaks termini in nicked duplex.
Gene References into Functions
  1. PARP2 is preferentially activated by poly(ADP-ribose) (PAR) and subsequently catalyzes branched PAR chain synthesis. PMID: 30104678
  2. data further suggest that ARTD2 would function in double strand break repair as a dimeric module, while in single strand break repair it would function as a monomer. PMID: 27708353
  3. Report a requirement for PARP2 in stabilizing replication forks that encounter base excision repair (BER) intermediates through Fbh1-dependent regulation of Rad51. Whereas PARP2 is dispensable for tolerance of cells to single stranded breaks or homologous recombination dysfunction, it is redundant with PARP1 in BER. PMID: 29467415
  4. PARP2 specifically limits the accumulation of the resection barrier factor 53BP1 at DNA damage sites, allowing efficient CtIP-dependent DNA end-resection PMID: 29036662
  5. either PARP1 or PARP2 are sufficient for near-normal XRCC1 recruitment at oxidative single-strand breaks PMID: 27965414
  6. Studies indicate that poly(ADP-ribose) polymerase 2 (PARP2) is involved in the differentiation of several cell types, including erythrocytes, T cells and adipocytes. PMID: 27087568

  9. The initial affinity between the PARP1, PARP2 and the DNA damaged site appears to influence both the size of the Poly(ADP-Ribose) synthesized and the time of residence of PARylated PARP1 and PARP2 on DNA damages. PMID: 26673720

  18. In complex with its inhibitor, the crystal structure of PARP2 alpha-helix 5 that contains glutamate residue Glu335 is closer to the active site than in both PARP1 and PARP3 and suggests a mechanism for a weak bias toward PARP2. PMID: 20092359
