Poly(ADP-ribose) in the skin and in melanomas.
Histology and histopathology, 2012 Cutaneous melanoma (CM) and uveal melanoma (UM) represent the most aggressive pigment cell tumor types. Our investigation examined the signaling molecule poly(ADP-ribose) (PAR) in CM and UM. We have demonstrated PAR in keratinocytes, sebocytes, hair follicles, endothelial cells and in subcutaneous adipocytes in the normal skin indicating that PAR may ...

RNA Regulation by Poly(ADP-Ribose) Polymerases [PDF]
Molecular Cell, 2015 Posttranscriptional regulation of RNA facilitates the fine-tuning of gene expression. It occurs through multiple pathways that include the nuclear processing of mRNA and its precursors, mRNA silencing, regulation of mRNA decay, and regulation of translation. Poly(ADP-ribose) polymerases (PARPs), enzymes that modify target proteins with ADP-ribose, play

Crystallographic and biochemical analysis of the mouse poly(ADP-ribose) glycohydrolase. [PDF]
PLoS ONE, 2014 Protein poly(ADP-ribosyl)ation (PARylation) regulates a number of important cellular processes. Poly(ADP-ribose) glycohydrolase (PARG) is the primary enzyme responsible for hydrolyzing the poly(ADP-ribose) (PAR) polymer in vivo.

PARP2 Is the Predominant Poly(ADP-Ribose) Polymerase in Arabidopsis DNA Damage and Immune Responses. [PDF]
PLoS Genetics, 2015 Poly (ADP-ribose) polymerases (PARPs) catalyze the transfer of multiple poly(ADP-ribose) units onto target proteins. Poly(ADP-ribosyl)ation plays a crucial role in a variety of cellular processes including, most prominently, auto-activation of PARP at ...

The Ups and Downs of Tannins as Inhibitors of Poly(ADP-Ribose)glycohydrolase
Molecules, 2011 DNA damage to cells activates nuclear poly(ADP-ribose)polymerases (PARPs) and the poly(ADP-ribose) (PAR) synthesized is rapidly cleaved into ADP-ribose (ADPR) by PAR glycohydrolase (PARG) action.

ARH Family of ADP-Ribose-Acceptor Hydrolases
Cells, 2022 The ARH family of ADP-ribose-acceptor hydrolases consists of three 39-kDa members (ARH1-3), with similarities in amino acid sequence. ARH1 was identified based on its ability to cleave ADP-ribosyl-arginine synthesized by cholera toxin.

Structural modeling of NAD+ binding modes to PARP-1
Вавиловский журнал генетики и селекции, 2017 The nuclear protein poly (ADP-ribose) polymerase-1 (PARP-1) plays an important role in the signaling and repair of DNA. PARP-1 catalyses covalent binding of poly (ADP-ribose) polymers with itself as well as with other acceptor proteins using NAD+ as a ...
