Human, Mouse

Synthesized peptide derived from human protein at AA range: 450-530

Expressed in lymphocyte-rich tissues, spleen, lymph nodes, peripheral blood lymphocytes and colonic mucosa (PubMed:11110709, PubMed:16809771) . Expressed in macrophages (PubMed:27796300) . Also expressed in nonhematopoietic tissues such as heart and skeletal muscle (PubMed:11110709, PubMed:16809771) . Isoform 2 is the predominant form (PubMed:11110709) . Most abundantly expressed in lymphomas with a brisk host inflammatory response (PubMed:11110709, PubMed:16809771) . In diffuse large B- cell lymphomas tumors, expressed specifically by malignant B-cells (PubMed:11110709, PubMed:16809771) .

WB, ELISA

PARP9 antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen.

ADP-ribosyltransferase which, in association with E3 ligase DTX3L, plays a role in DNA damage repair and in immune responses including interferon-mediated antiviral defenses (PubMed:16809771, PubMed:23230272, PubMed:26479788, PubMed:27796300) . Within the complex, enhances DTX3L E3 ligase activity which is further enhanced by PARP9 binding to poly (ADP- ribose) (PubMed:28525742) . In association with DTX3L and in presence of E1 and E2 enzymes, mediates NAD (+) -dependent mono-ADP- ribosylation of ubiquitin which prevents ubiquitin conjugation to substrates such as histones (PubMed:28525742) . During DNA repair, PARP1 recruits PARP9/BAL1-DTX3L complex to DNA damage sites via PARP9 binding to ribosylated PARP1 (PubMed:23230272) . Subsequent PARP1-dependent PARP9/BAL1-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites (PubMed:23230272, PubMed:28525742) . In response to DNA damage, PARP9-DTX3L complex is required for efficient non-homologous end joining (NHEJ) ; the complex function is negatively modulated by PARP9 activity (PubMed:28525742) . Dispensable for B-cell receptor (BCR) assembly through V (D) J recombination and class switch recombination (CSR) (By similarity) . In macrophages, positively regulates pro-inflammatory cytokines production in response to IFNG stimulation by suppressing PARP14-mediated STAT1 ADP-ribosylation and thus promoting STAT1 phosphorylation (PubMed:27796300) . Also suppresses PARP14-mediated STAT6 ADP-ribosylation (PubMed:27796300) .
