PARP catalysed ADP-ribosylation is a post-translational modification involved in several physiological and pathological processes, including cellular stress. In order to visualise both Poly-, and Mono-, ADP-ribosylation in vivo, we engineered specific fluorescent probes. Using them, we show that amino-acid starvation triggers an unprecedented display of mono-ADP-ribosylation that governs the formation ... read more of Sec body, a recently identified stress assembly that forms in Drosophila cells. We show that dPARP16 catalytic activity is necessary and sufficient for both amino-acid starvation induced mono-ADP-ribosylation and subsequent Sec body formation and cell survival. Importantly, dPARP16 catalyses the modification of Sec16, a key Sec body component, and we show that it is a critical event for the formation of this stress assembly. Taken together our findings establish a novel example for the role of mono-ADP-ribosylation in the formation of stress assemblies, and link this modification ...
Two nicotinamide adenine dinucleotide (NAD(+)) analogues modified at the 6 position of the purine ring were synthesized, and their substrate properties toward Aplysia californica ADP-ribosyl cyclase were investigated. 6-N-Methyl NAD(+) (6-N-methyl nicotinamide adenosine 5-dinucleotide 10) hydrolyzes to give the linear 6-N-methyl ADPR (adenosine 5-diphosphoribose, 11), whereas 6-thio NHD(+) (nicotinamide 6-mercaptopurine 5-dinucleotide, 17) generates a cyclic dinucleotide. Surprisingly, NMR correlation spectra confirm this compound to be the N1 cyclic product 6-thio N1-cIDPR (6-thio cyclic inosine 5-diphosphoribose, 3), although the corresponding 6-oxo analogue is well-known to cyclize at N7. In Jurkat T cells, unlike the parent cyclic inosine 5-diphosphoribose N1-cIDPR 2, 6-thio N1-cIDPR antagonizes both cADPR- and N1-cIDPR-induced Ca(2+) release but possesses weak agonist activity at higher concentration. 3 is thus identified as the first C-6 modified cADPR (cyclic adenosine 5-diphosphoribose)

BACKGROUND: Cyclic ADP-ribose (cADPR) has been shown to act as a potent cytosolic mediator in a variety of tissues, regulating the release of Ca2+ from intracellular stores by a mechanism that involves ryanodine receptors. There is controversy over the effects of cADPR in cardiac muscle, although one possibility is that endogenous cADPR increases the Ca2+ sensitivity of Ca2+-induced Ca2+ release (CICR) from the sarcoplasmic reticulum. We investigated this possibility using 8-amino-cADPR, which has been found to antagonize the Ca2+-releasing effects of cADPR on sea urchin egg microsomes and in mammalian cells (Purkinje neurons, Jurkat T cells, smooth muscle and PC12 cells). RESULTS: In intact cardiac myocytes isolated from guinea-pig ventricle, cytosolic injection of 8-amino-cADPR substantially reduced contractions and Ca2+ transients accompanying action potentials (stimulated at 1Hertz). These reductions were not seen with injection of HEPES buffer, with heat-inactivated 8-amino-cADPR, or in cells

ADP-ribosylation of proteins occurs in many eukaryotes, and it is also the mechanism of action of a growing number of important bacterial toxins. To date, however, there is only one well-characterized ADP-ribosylation system where the ADP-ribosyltransferase and the substrate protein are both bacterial in origin, namely within the nitrogen-fixing bacterium Rhodospirillum rubrum. The present paper demonstrates the endogenous ADP-ribosylation of two proteins of Mr 32,000 and 20,000 within Pseudomonas maltophilia, a Gram-negative aerobe. The proteins have been partially purified: two apparently separate species of modified protein can be separated by ion-exchange chromatography and gel filtration (V0 and Mr 158,000 - Vi). The substrate protein(s) either has, or is co-eluted with, NAD+ glycohydrolase activity. The modification is mono-ADP-ribosyl in nature. The linkage between the acceptor amino acid and the ADP-ribose moiety is alkali-labile and stable to hydroxylamine, possibly indicating an ...
The quantitative determination of pertussis-toxin-sensitive guanine-nucleotide-binding proteins (G-proteins) in cell membranes is still a problem. Pertussis-toxin-catalysed [32P]ADP-ribosylation strongly relies on the substrate quality of the alpha-subunits and is influenced by the concentration of nucleotides, beta gamma-subunits, the physicochemical properties of the membranes influencing the availability of Gi alpha for pertussis toxin, and covalent modification of Gi alpha. Quantification of immunoreactive material on Western blots can be only imprecisely performed by two-dimensional densitometry. In order to generate a method for quantification of pertussis-toxin-sensitive G-proteins in membranes we have developed a fast and sensitive radioimmunoassay. The C-terminal decapeptide of retinal transducin alpha (KENLKDCGLF) was 125I-labelled and used as tracer. Polyclonal antiserum (DS 4) was raised against this peptide. Gi alpha proteins were determined by competition of solubilized membranes ...

Implications for Modulating the Function of Sir2 Proteins. The p53 tumor suppressor protein has been implicated to be a regulated target for both acetylation and deacetylation in vivo. In particular, several studies have demonstrated that the targeted acetylation of lysine residues at the C terminus of p53 by the transcription coactivators CBP/p300 and P/CAF promotes the stability and transcriptional activation properties of p53 (20-23). More recent studies have shown that the Sir2 homologue from humans, SIRT1, specifically deacetylates p53 in vivo to negatively regulate its activities associated with cellular senescence, apoptosis, and DNA repair (24-27). In light of these recent findings, it may be attractive to develop specific inhibitors to SIRT1 to elevate p53 function in cancer cells. In addition, Sir2-specific inhibitors may be useful as reagents to probe other functions for Sir2 proteins in vivo. Using a cell-based chemical screen, Schreiber and colleagues (28) have identified several ...

Clostridium botulinum C3 exoenzyme inactivates the small GTP-binding protein family Rho by ADP-ribosylating asparagine 41, which depolymerizes the actin cytoskeleton. C3 thus represents a major family of the bacterial toxins that transfer the ADP-ribose moiety of NAD to specific amino acids in acceptor proteins to modify key biological activities in eukaryotic cells, including protein synthesis, differentiation, transformation, and intracellular signaling. The 1.7 A resolution C3 exoenzyme structure establishes the conserved features of the core NAD-binding beta-sandwich fold with other ADP-ribosylating toxins despite little sequence conservation. Importantly, the central core of the C3 exoenzyme structure is distinguished by the absence of an active site loop observed in many other ADP-ribosylating toxins. Unlike the ADP-ribosylating toxins that possess the active site loop near the central core, the C3 exoenzyme replaces the active site loop with an alpha-helix, alpha3. Moreover, structural ...
ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. Improper ADP-ribosylation has been implicated in some forms of cancer. It is also the basis for the toxicity of bacterial compounds such as cholera toxin, diphtheria toxin, and others. The first suggestion of ADP-ribosylation surfaced during the early 1960s. At this time, Pierre Chambon and coworkers observed the incorporation of ATP into hen liver nuclei extract. After extensive studies on the acid insoluble fraction, several different research laboratories were able to identify ADP-ribose, derived from NAD+, as the incorporated group. Several years later, the enzymes responsible for this incorporation were identified and given the name poly (ADP-ribose) polymerase. Originally, this group was thought to be a linear sequence of ADP-ribose units ...
Ecto-ADP-ribosyltransferase 4 is an enzyme that in humans is encoded by the ART4 gene. ART4 has also been designated as CD297 (cluster of differentiation 297). This gene encodes a protein that contains a mono-ADP-ribosylation (ART) motif. It is a member of the ADP-ribosyltransferase gene family but enzymatic activity has not been demonstrated experimentally. Antigens of the Dombrock blood group system are located on the gene product, which is glycosylphosphatidylinositol-anchored to the erythrocyte membrane. Allelic variants, some of which lead to adverse transfusion reactions, are known. Several antigens have been recognised in this family. These are DO*A, DO*JO1, DO*A-WL, DO*DOYA, DO*B, DO*B-WL, DO*B-SH-Q149K, DO*B-(WL)-I175N, DO*HY1, DO*HY2 and DO*DOMR. Model organisms have been used in the study of ART4 function. A conditional knockout mouse line called Art4tm1a(KOMP)Wtsi was generated at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen ...
NAD glycohydrolases are enzymes that catalyze the hydrolysis of NAD to produce ADP-ribose and nicotinamide. Regulation of these enzymes has not been fully elucidated. We have identified a NAD-glycohydrolase activity associated with the outer surface of the plasma membrane in human lung epithelial cell line A549. This activity is negatively regulated by its substrate beta-NAD but not by alpha-NAD. Partial restoration of NADase activity after incubation of the cells with arginine or histidine, known ADP-ribose acceptors, suggests that inhibition be regulated by ADP-ribosylation. A549 do not undergo to apoptosis upon NAD treatment indicating that this effect be likely mediated by a cellular component(s) lacking in epithelial cells. ...

Nicotinic acid-adenine dinucleotide phosphate (NAADP) is a newly described Ca2+-mobilizing nucleotide that appears to target intracellular Ca2+-release channels distinct from those sensitive to inositol trisphosphate or ryanodine/cyclic ADP-ribose. Little, however, is known concerning the regulation of cellular NAADP levels. In the present study, we have characterized the metabolism of NAADP by brain membranes. From HPLC and MS analyses we show that loss of NAADP was associated with the appearance of a major product that is likely to be nicotinic acid-adenine dinucleotide (NAAD), the dephosphorylated form of NAADP. Dephosphorylation of NAADP, but not 3-NAADP, was dramatically attenuated by Ca2+ chelators and stimulated by Ca2+ over a physiological range in a calmodulin-insensitive manner. In contrast, NADP was metabolized predominantly to ADP-ribose phosphate via glycohydrolase activity, although slower Ca2+-dependent dephosphorylation of both NADP and 2-AMP could also be demonstrated. This is the
CD38 is a 42-kilodalton glycoprotein expressed extensively on B and T lymphocytes. CD38 exhibits a structural homology to Aplysia adenosine diphosphate (ADP)-ribosyl cyclase. This enzyme catalyzes the synthesis of cyclic ADP-ribose (cADPR), a metabolite of nicotinamide adenine dinucleotide (NAD +) with calcium-mobilizing activity. A complementary DNA encoding the extracellular domain of murine CD38 was constructed and expressed, and the resultant recombinant soluble CD38 was purified to homogeneity. Soluble CD38 catalyzed the formation and hydrolysis of cADPR when added to NAD+. Purified cADPR augmented the proliferative response of activated murine B cells, potentially implicating the enzymatic activity of CD38 in lymphocyte function ...

Abstract: Cellular cross-talk between ubiquitination and other posttranslational modifications contributes to the regulation of numerous processes. One example is ADP-ribosylation of the carboxyl terminus of ubiquitin by the E3 DTX3L/ADP-ribosyltransferase PARP9 heterodimer, but the mechanism remains elusive. Here, we show that independently of PARP9, the conserved carboxyl-terminal RING and DTC (Deltex carboxyl-terminal) domains of DTX3L and other human Deltex proteins (DTX1 to DTX4) catalyze ADP-ribosylation of ubiquitins Gly76. Structural studies reveal a hitherto unknown function of the DTC domain in binding NAD+. Deltex RING domain recruits E2 thioesterified with ubiquitin and juxtaposes it with NAD+ bound to the DTC domain to facilitate ADP-ribosylation of ubiquitin. This ubiquitin modification prevents its activation but is reversed by the linkage nonspecific deubiquitinases. Our study provides mechanistic insights into ADP-ribosylation of ubiquitin by Deltex E3s and will enable future ...
