WebbMethods of identifying agents which alter the NAD-dependent acetylation status and mono-ADP-ribosylation of nuclear proteins are disclosed. The methods further include identifying agents which alter the life span or aging of a cell or an organism by determining the level of NAD-dependent acetylation and/or ADP ribosylation of a nuclear protein.

WebbPertussis toxin (PTX) catalyzes the ADP-ribosylation of the α-subunit of GTPbinding proteins (G-proteins) in the presence of NAD +. Pertussis toxin also decreases the electrophoretic mobility of the a-subunit on urea SDS PAGE. This effect of PTX has been suggested to be a property of the toxin different from its ability to catalyze ADP ... 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 … Visa mer 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 … Visa mer Many different amino acid side chains have been described as ADP-ribose acceptors. From a chemical perspective, this modification … Visa mer Cancer PARP1 is involved in base excision repair (BER), single- and double-strand break repair, and … Visa mer The source of ADP-ribose for most enzymes that perform this modification is the redox cofactor NAD . In this transfer reaction, the N-glycosidic bond of NAD that bridges the ADP … Visa mer Apoptosis During DNA damage or cellular stress PARPs are activated, leading to an increase in the … Visa mer • Histone code • Cell signaling • PARP-1 • Cholera toxin Visa mer WebbAbstract. G protein-coupled receptors can potentially activate phospholipase D (PLD) by a number of routes. We show here that the native M3 muscarinic receptor in 1321N1 cells and an epitope-tagged M3 receptor expressed in COS7 cells substantially utilize an ADP-ribosylation factor (ARF)-dependent route of PLD activation. husker chemical
