WebbADP-ribosylation is governed by ADP-ribosyltransferases and a subclass of sirtuins (writers), is sensed by proteins that contain binding modules (readers) that recognize specific parts of the ADP-ribosyl posttranslational modification, and is removed by ADP-ribosylhydrolases (erasers). 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 represents protein glycosylation: … Visa mer • Histone code • Cell signaling • PARP-1 • Cholera toxin 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 amount of poly(ADP-ribose) and a … Visa mer Cancer PARP1 is involved in base excision repair (BER), single- and double-strand break repair, and chromosomal stability. It is also involved in transcriptional regulation through its facilitation of protein–protein interactions. … Visa mer

HPF1-dependent histone ADP-ribosylation triggers chromatin

WebbConsistent with a functional cross-talk between ADP-ribosylation and other histone tail modifications, acetylation of H4K16 inhibits ADP-ribosylation by PARP1. Taken together, our computational and experimental results provide strong evidence that PARP1 modifies important regulatory lysines of the core histone tails. WebbA matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) method that facilitates the discovery and validation of ADPr site motifs is presented and a minimal 5-mer peptide sequence is identified that is sufficient to drive PARP14 specific activity while highlighting the importance of the adjacent residues inPARP14 targeting.
