PARG Screening & Profiling
PARG (Poly(ADP-ribose) glycohydrolase) is a protein that plays a crucial role in DNA repair processes, including base excision repair and single-strand break repair. Its function involves removing poly(ADP-ribose) (PAR) from proteins that have been modified by PAR polymerases (PARPs), which enables DNA repair. Dysregulation of PARG activity has been implicated in various diseases, including cancer. Targeting PARG for therapy has ...
Cellular PARylation: From Inquiry to Insight in Drug Discovery
Summary
Inhibitors of poly (ADP-ribose) polymerases (PARPs) have been game-changing in cancer therapy, demonstrating the potential efficacy of synthetic lethal drugs targeting complementary pathways within the DNA damage response network. However, the evaluation of poly-ADP-ribosylation in intact cells is difficult, slowing the development of candidate drugs. BPS Bioscience’s LysA™ Universal PARylation Assay Kit quantifies...
PARP Assays
Poly(ADP-ribose) polymerase (PARP) proteins play a crucial role in DNA repair mechanisms within cells. These enzymes are involved in the repair of single-strand DNA breaks through the base excision repair pathway. Inhibition of PARP proteins has emerged as a promising strategy in cancer therapy, particularly in tumors with defective DNA repair mechanisms, such as those with BRCA mutations. When PARP is inhibited, it prevents the repair of single-strand breaks, leading to th...
Setting a Trap for PARP1 and PARP2
Summary
PARP1 and PARP2 operate in DNA damage response (DDR) by sensing single breaks in DNA and by recruiting the repair machinery through poly-ADP ribosylation of histones and other proteins. PARP inhibitors are cytotoxic to cancer cells deficient in repair pathways that are complementary to PARP pathways, and it has been shown that some of these inhibitors act by trapping PARP1/2 onto the DNA, preventing repair and leading to cell death. Thus, DNA tra...
PARP/PARPTrap™ Screening & Profiling
PARP (Poly ADP-Ribose Polymerase) proteins are a large family of 17 members that catalyze the ADP-ribosylation of proteins and DNA. PARPs are part of a network of 150 proteins involved in the DNA damage response, which constantly scan and repair DNA to maintain genome integrity. The PARP proteins are involved in a wide range of biological functions: DNA repair, chromatin remodeling, mitotic spindle assembly, regulati...
DNA Replication & Repair Screening & Profiling
DNA replication and repair are crucial processes for maintaining genetic integrity and ensuring the accurate transmission of genetic information necessary for cell division, growth, and development. Errors in replication can lead to mutations, resulting in genetic disorders and increased susceptibility to diseases like cancer. DNA repair mechanisms play a vital role in identifying and correcting damage to the ...
