Heat stress reduces poly(ADPR)polymerase expression in rat testis.
Poly(ADPR)polymerase (PARP) is a chromatin-associated enzyme with a presumptive role in DNA repair during replication and recovery from strand breaks caused by genotoxic agents. It catalyses the attachment and elongation of ADPribose polymers (pADPR) to a variety of acceptor proteins (including PARP itself, and histones) and is particularly active in the testis where its expression varies accor...
متن کاملSerine is the major residue for ADP-ribosylation upon DNA damage
Poly(ADP-ribose) polymerases (PARPs) are a family of enzymes that synthesise ADP-ribosylation (ADPr), a reversible modification of proteins that regulates many different cellular processes. Several mammalian PARPs are known to regulate the DNA damage response, but it is not clear which amino acids in proteins are the primary ADPr targets. Previously, we reported that ARH3 reverses the newly dis...
متن کاملStructure/Function Analysis of PARP-1 in Oxidative and Nitrosative Stress-Induced Monomeric ADPR Formation
Poly adenosine diphosphate-ribose polymerase-1 (PARP-1) is a multifunctional enzyme that is involved in two major cellular responses to oxidative and nitrosative (O/N) stress: detection and response to DNA damage via formation of protein-bound poly adenosine diphosphate-ribose (PAR), and formation of the soluble 2(nd) messenger monomeric adenosine diphosphate-ribose (mADPR). Previous studies ha...
متن کاملIdentification of the ADPR binding pocket in the NUDT9 homology domain of TRPM2
Activation of the transient receptor potential melastatin 2 (TRPM2) channel occurs during the response to oxidative stress under physiological conditions as well as in pathological processes such as ischemia and diabetes. Accumulating evidence indicates that adenosine diphosphate ribose (ADPR) is the most important endogenous ligand of TRPM2. However, although it is known that ADPR binds to the...
متن کاملSynthesis of DNA and poly(adenosine diphosphate ribose) in normal and chronic lymphocytic leukemia lymphocytes.
Peripheral blood lymphocytes were isolated from 9 patients with chronic lymphocytic leukemia (CLL) and 12 normal control donors. The cells were assayed for synthesis of DNA and poly-(adenosine diphosphate ribose) (poly[ADPR]) immediately after isolation and on successive days following their treatment with phytohemagglutinin (PHA). Two different techniques were used to measure DNA synthesis. In...
