詳細
Research area: Cell Signaling
Human PARP1 (GenBank Accession No. NM_001618), full length with N-terminal GST tag, MW = 140 kDa, expressed in a Baculovirus infected Sf9 cell expression system. Poly [ADP-ribose] polymerase 1 (PARP1) belongs to the DNA-dependent nuclear enzyme superfamily. Its structure includes an N-terminal with three zinc finger DNA-binding domains, an auto-modification domain with BRCT motif and a WGR domain having conserved tryptophan, glycine, and arginine residues, and a C-terminal catalytic domain with PARP signature sequence.

アプリケーション
PARP1 Active human has been used in GST-PARP1 pulldown, to study the alterations in protein-protein interactions of sex determining region Y-box 2 (SOX2) upon O-GlcNAcylation. It has also been used in in vitro PARylation assay to investigate the effect of NR1D1 on DNA repair after damage induced by doxorubicin in breast cancer cells. It is useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
生物化学的／生理学的作用
PARPs comprise a set of enzymes that govern cellular processes such as DNA damage response, cell metabolism, chromatin remodeling, and transcriptional regulation. PARP1 detects and mends DNA breaks via base excision repair when DNA damage occurs. In the absence of PARP1 activity, damaged DNA accumulates, leading to impaired DNA replication.
単位の定義
One unit of PARP incorporates 100 pmoles of poly(ADP) in 1 minute (room temperature) from NAD into acid-insoluble form.
物理的形状
Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 50% glycerol and 3 mM DTT.

Liver X receptor α (LXRα) controls a set of key genes involved in cholesterol metabolism. However, the molecular mechanism of this regulation remains unknown. The regulatory role of poly(ADP-ribose) polymerase 1 (PARP1) in cholesterol metabolism in the liver was examined.

Root organogenesis involves cell division, differentiation and expansion. The molecular mechanisms regulating root development are not fully understood. In this study, we identified poly(adenosine diphosphate (ADP)-ribose) polymerases (PARPs) as new players in root development. PARP catalyzes poly(ADP-ribosyl)ation of proteins by

The nucleoside analog 5-aza-2'-deoxycytidine (5-aza-dC) is used to treat some hematopoietic malignancies. The mechanism of cell killing depends upon DNMT1, but is otherwise not clearly defined. Here we show that PARP1 forms covalent DNA adducts in human lymphoblast or fibroblasts
