Intracellular Mono-ADP-Ribosylation in Signaling and Disease
A key process in the regulation of protein activities and thus cellular signaling pathways is the modification of proteins by post-translational mechanisms. Knowledge about the enzymes (writers and erasers) that attach and remove post-translational modifications, the targets that are modified and the functional consequences elicited by specific modifications, is crucial for understanding cell b...
متن کاملReversing ADP-ribosylation
The modification of serines by molecules of ADP-ribose plays an important role in signaling that the DNA in a cell has been damaged and needs to be repaired.
متن کاملPoly-ADP-ribosylation signaling during DNA damage repair.
Poly-ADP-ribosylation is a post-translational modification generated in high amounts by poly-ADP-ribose polymerases (PARPs) in response to cellular stress, especially genotoxic stimuli. DNA damage-induced PARylation significantly changes local chromatin structure and triggers the accumulation of several DNA damage response (DDR) proteins at the DNA lesions. In this review, we will discuss the r...
متن کاملTuning IL-2 signaling by ADP-ribosylation of CD25
Control of immunologic tolerance and homeostasis rely on Foxp3(+)CD4(+)CD25(+) regulatory T cells (Tregs) that constitutively express the high affinity receptor for Interleukin-2, CD25. Tregs proliferate in response to injections of IL-2/anti-IL-2 antibody complexes or low doses of IL-2. However, little is known about endogenous mechanisms that regulate the sensitivity of CD25 to signaling by I...
متن کاملADP-ribosylation of nuclear proteins.
ADP-ribosylation can be defined as the postsynthetic modification of protein by the covalent attachment of the ADP-ribose moiety of NAD+. ADP-ribosylation of elongation-factor Tu is responsible for the inhibition of protein synthesis by both diptheria and Pseudomonas aeroginosa toxins (Hilz & Stone, 1976). The activation of membrane adenylate cyclase by cholera toxin is thought to occur by ADP-...
