Poly [ADP-ribose] polymerase 1 - mouse (Parp1)

nvolved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150. With EEF1A1 and TXK, forms a complex that acts as a T-helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFN-gamma to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production. Required for PARP9 and DTX3L recruitment to DNA damage sites. PARP1-dependent PARP9-DTX3L-mediated ubiquitination promotes the rapid and specific recruitment of 53BP1/TP53BP1, UIMC1/RAP80, and BRCA1 to DNA damage sites. Mediates serine ADP-ribosylation of target proteins following interaction with HPF1; HPF1 conferring serine specificity. Mediates the poly(ADP-ribosyl)ation of histones in a HPF1-dependent manner. Involved in the synthesis of ATP in the nucleus, together with NMNAT1, PARG and NUDT5. Nuclear ATP generation is required for extensive chromatin remodeling events that are energy-consuming.
Recommended sample types are human EDTA plasma and serum. A range of additional sample types are compatible with the technology (PEA), including citrate plasma, heparin plasma, cerebrospinal fluid, (CSF), tissue and cell lysates, fine needle biopsis, microdialysis fluid, cell culture media, dried blood spots, synovial fluid, saliva, plaque extract and microvesicles. Please note that protein expression levels are expected to vary in different sample types. Certain assays are differentially affected by interfering substances such as hemolysate. Download any of our Data Validation documents or contact firstname.lastname@example.org for more information.
NOTE: The calibrator curve below shows the performance of the assay with the estimated sensitivity and dynamic range parameters indicated. These curves are generated during the assay validation process using recombinant antigens. Please note that when analyzing biological samples the data generated will be given in the form of relative quantification (NPX values) and cannot be converted to absolute protein concentrations. For more info about NPX measurements, please visit our FAQ page.

Detectability in different mouse sample matrices
The figure above shows the overall detectability of the specified assay in a range of different mouse sample types. Detectability in each sample matrix is presented as the mean % of all samples included in the validation studies that could be measured above the limit of detection (LOD).
Dilution of samples may be necessary for some sample matrices other than plasma or serum to achieve optimal assay performance – the data shown above represents the values obtained at the optimal dilution identified in each case. Details regarding possible dilutions should be discussed with your Olink representative prior to commencing the study. The data is compiled from multiple studies comprising a range of healthy and disease samples, including samples from genetically modified mouse lines in some cases.
(Note: CSF = cerebrospinal fluid; BAL = bronchoalveolar lavage).
- Within run precision Coefficient of Variation (CV)
- Between run precision Coefficient of Variation (CV)
Precision (repeatability) is calculated from linearized NPX values over LOD.
