[[https://www.uniprot.org/uniprot/PARG_RAT PARG_RAT]] Poly(ADP-ribose) synthesized after DNA damage is only present transiently and is rapidly degraded by poly(ADP-ribose) glycohydrolase. PARG acts both as an endo- and exoglycosidase, releasing PAR of different length as well as ADP-ribose monomers. Required for retinoid acid-dependent gene transactivation, probably by dePARsylating histone demethylase KDM4D, allowing chromatin derepression at RAR-dependent gene promoters (By similarity).

== Publication Abstract from PubMed ==
+
-
Reversible post-translational modification by poly(ADP-ribose) (PAR) regulates chromatin structure, DNA repair and cell fate in response to genotoxic stress. PAR glycohydrolase (PARG) removes PAR chains from poly ADP-ribosylated proteins to restore protein function and release oligo(ADP-ribose) chains to signal damage. Here we report crystal structures of mammalian PARG and its complex with a substrate mimic that reveal an open substrate-binding site and a unique 'tyrosine clasp' enabling endoglycosidic cleavage of branched PAR chains.
