|Other Names||Poly(ADP-ribose) glycohydrolase, PARG|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP7283b was selected from the C-term region of human Parg. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Poly(ADP-ribose) synthesized after DNA damage is only present transiently and is rapidly degraded by poly(ADP-ribose) glycohydrolase (PubMed:23102699). PARG acts both as an endo- and exoglycosidase, releasing PAR of different length as well as ADP- ribose monomers (PubMed:23102699). Required for retinoid acid- dependent gene transactivation, probably by dePARsylating histone demethylase KDM4D, allowing chromatin derepression at RAR- dependent gene promoters (PubMed:23102699). Involved in the synthesis of ATP in the nucleus, together with PARP1, NMNAT1 and NUDT5 (PubMed:27257257). Nuclear ATP generation is required for extensive chromatin remodeling events that are energy-consuming (PubMed:27257257).|
|Cellular Location||Isoform 1: Nucleus Note=Colocalizes with PCNA at replication foci. Relocalizes to the cytoplasm in response to DNA damage Isoform 3: Cytoplasm. Isoform 5: Mitochondrion matrix.|
|Tissue Location||Ubiquitously expressed.|

Poly(ADP-ribose) glycohydrolase (PARG) is the major enzyme responsible for the catabolism of poly(ADP-ribose), a reversible covalent-modifier of chromosomal proteins. The protein is found in many tissues and may be subject to proteolysis generating smaller, active products.
