11. Our study differentiates the functions of PARP-2 domains from those of PARP-1, the other major DDR-PARP, and highlights the specialization of the multi-domain architectures of DDR-PARPs.

12. Interaction of PARP-2 with AP site containing DNA

13. Identification of ADP-ribosylation sites in PARP2 and the determination of the extent ofpoly(ADP-ribosyl)ated residues in this protein was performed.

14. Nuclear Smad function is negatively regulated by PARP-1 that is assisted by PARP-2 and positively regulated by PARG during the course of TGFB signaling.

15. the depletion of PARP-2 leads to lower HDL levels which represent a risk factor to cardiovascular diseases.

16. these findings propose a novel mechanism of PARP-2 in transcriptional regulation involving specific protein-protein interactions and highlight the importance of PARP-2 in the regulation of cell cycle progression.

17. PARP-1 (but not PARP-2) poly(ADP) ribosylates Snail1, both in vivo and in vitro, and interacts with Snail1, an association that is sensitive to PARP inhibitors.

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.

19. The PARP-2 gene might be associated with azoospermia by meiotic arrest

20. PARP-1 and PARP-2 act as positive regulators of genomic stability in eukaryotic cells by counteracting topoisomerase I-induced DNA damage

Mouse (Murine) Poly (ADP-Ribose) Polymerase 2 (PARP2) interaction partners

1. PARP2 is preferentially activated by poly(ADP-ribose) (PAR) and subsequently catalyzes branched PAR chain synthesis.

2. Peripheral T-cell number was not affected in single PARP-2-deficient mice. Double-deficiency in PARP-1/PARP-2 in T-cells led to highly aggressive T-cell lymphomas.

3. PARP2 protein deficiency protected mice from Concanavalin A -induced Liver Damage.

4. Activation of either PARP-1 or -2 is likely to play a role in muscle protein catabolism via oxidative stress, NF-kappaB signaling, and enhanced proteasomal degradation in cancer-induced cachexia.

5. PARP1/2 inhibitor simmiparib causes growth inhibition in cancer cell- or tissue-derived xenografts in nude mice.

6. The findings highlight specific non-overlapping functions of PARP1 and PARP2 at H2AX-deficient chromatin during replicative phases of the cell cycle and uncover a unique requirement for PARP1 in nonhomologous end-joining-deficient cells.

7. Data show reduced tumor burden through increased oxidative stress in lung adenocarcinoma cells of PARP-1 and PARP-2 knockout mice.

8. PARP-2 has an essential role in erythropoiesis by limiting replicative stress in erythroid progenitors.

9. PARP-1 and -2 play a role in cancer-induced cachexia, thus selective pharmacological inhibition of PARP-1 and -2 may be of interest in clinical settings

10. the depletion of PARP-2 leads to lower HDL levels which represent a risk factor to cardiovascular diseases.

11. This study represents the first description of a significant role for PARP-2 in neuroinflammation and neurological dysfunction in Experimental autoimmune encephalomyelitis

12. our data show that PARP-2 can directly regulate base excision repair proteins

13. Our results show that Parp-2 plays essential roles in the surveillance of genome integrity of stem cell hematopoiesis by orchestrating DNA repair and restraining p53-induced and Puma-mediated apoptosis.

14. PARP2 activity mobilizes intracellular TRPM2 channels in a Parp1-/- background.

15. Identify PARP-2 as a mediator of doxorubicin toxicity by regulating vascular SIRT1 activity and mitochondrial biogenesis.

16. Inhibition of PARP1 and PARP2 (by genetic or pharmacological means) leads to increased TOP2B activity in elongating spermatids.

17. PARP-2 deletion in mice increases SIRT1 levels, promotes energy expenditure, and increases mitochondrial content.

19. crystal structure of the catalytic fragment of murine PARP-2, at 2.8 A resolution

20. We conclude that PARP-2 contributes substantially to nuclear translocation of AIF and infarct size after transient focal cerebral ischemia in male mice, but that protection is disproportionate to the attenuation of overall PARP activity.

Arabidopsis thaliana Poly (ADP-Ribose) Polymerase 2 (PARP2) interaction partners

1. We found that larger deletions of >20 bp predominated after DSB repair in ku80 and ku80 parp1 parp2 mutants, corroborating with a role of KU in preventing DSB end resection. Deletion lengths did not significantly differ between ku80 and ku80 parp1 parp2 mutants, suggesting that a KU- and PARP-independent b-NHEJ mechanism becomes active in these mutants.
