Poly(ADP-ribosyl)ation is a post-translational protein modification involved in
the regulation of important cellular functions including DNA repair,
transcription, mitosis and apoptosis. The amount of poly(ADP-ribosyl)ation (PAR)
in cells reflects the balance of synthesis, mediated by the PARP protein family,
and degradation, which is catalyzed by a glycohydrolase, PARG. Many of the
proteins mediating PAR metabolism possess specialised high affinity PAR-binding
modules that allow the efficient sensing or processing of the PAR signal. The
identification of four such PAR-binding modules and the characterization of a
number of proteins utilising these elements during the last decade has provided
important insights into how PAR regulates different cellular activities. The
macrodomain represents a unique PAR-binding module which is, in some instances,
known to possess enzymatic activity on ADP-ribose derivatives (in addition to
PAR-binding). The most recently discovered example for this is the PARG protein,
and several available PARG structures have provided an understanding into how the
PARG macrodomain evolved into a major enzyme that maintains PAR homeostasis in
living cells.
