Poly (ADP-ribose) polymerase (PARP), also termed poly (ADP-ribose) synthetase (PARS) is a nuclear enzyme with a wide range of functions, including regulation of DNA repair, cell differentiation, and gene expression. More than a decade after the identification of PARP-like enzymatic activities in mammalian cells, a novel role was proposed for this enzyme, mediating a suicidal mechanism triggered by DNA strand breakage. This hypothesis has since become a controversial centerpiece of the PARP field, with many experimental systems both confirming and extending the PARP suicide theory.
