Studying Catabolism of Protein ADP-Ribosylation [PDF]
Protein ADP-ribosylation is a conserved posttranslational modification that regulates many major cellular functions, such as DNA repair, transcription, translation, signal transduction, stress response, cell division, aging, and cell death. Protein ADP-ribosyl transferases catalyze the transfer of an ADP-ribose (ADPr) group from the β-nicotinamide ...

Serine 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.

PARP1 ADP-ribosylates lysine residues of the core histone tails [PDF]
The chromatin-associated enzyme PARP1 has previously been suggested to ADP-ribosylate histones, but the specific ADP-ribose acceptor sites have remained enigmatic.

Are guanine nucleotide binding proteins a distinct class of regulatory proteins? [PDF]
Proteins which bind guanine nucleotides are found in a diverse set of key regulatory positions. They are involved in hormone action, visual transduction, protein synthesis and microtubule assembly. In addition to their ability to bind guanine nucleotides

Background and Purpose Endometriosis is a chronic, hormone‐dependent disorder characterized by ectopic implantation of endometrial tissue, often accompanied by pain and infertility. Although the progesterone receptor modulator RU486 is effective for pain relief, its impact on lesion regression is limited, possibly due to apoptosis resistance and ...

Changes in NAD/ADP-ribose metabolism in rectal cancer
The extent of ADP-ribosylation in rectal cancer was compared to that of the corresponding normal rectal tissue. Twenty rectal tissue fragments were collected during surgery from patients diagnosed as having rectal cancer on the basis of pathology results.

Automodification of N‐terminal serine residues facilitates PARP2 release from DNA
PARP2 is involved in detecting DNA damage and its N‐terminal role is largely unknown. Based on biochemical and biophysical data, our findings suggest that in the presence of HPF1, N‐terminal serine 8 and 73 are enriched in auto‐ADP‐ribosylation. Our results provide insight into the mechanistic role of PARP2 N‐terminus in the PARylation‐dependent ...

PARP9 and PARP14 cross-regulate macrophage activation via STAT1 ADP-ribosylation
Despite the global impact of macrophage activation in vascular disease, the underlying mechanisms remain obscure. Here we show, with global proteomic analysis of macrophage cell lines treated with either IFNγ or IL-4, that PARP9 and PARP14 regulate ...

Cytohesin 2/ARF6 regulates preadipocyte migration through the activation of ERK1/2 [PDF]
Preadipocyte migration is vital for the development of adipose tissue, which plays a crucial role in lipid metabolism. ADP-ribosylation factor 6 (ARF6) small GTPase, which regulates membrane trafficking, is activated by GTP-exchange factors (GEFs) such ...

ABSTRACT The plant endomembrane system and vesicle trafficking are central to plant immunity, mediating the targeted delivery and recycling of defence molecules during pathogen attack. Here, we investigated the functional role of soybean Vacuole Membrane Protein 1 (GmVMP1) in mediating resistance against soybean cyst nematode (SCN, Heterodera glycines).
