Spotlight on PARP

Poly (ADP-ribose) polymerase (PARP) is a 17 member protein family, involved in DNA repair and programmed cell death. PARP proteins detect single strand DNA breaks (SSB) and initiate the mechanism responsible for base excision repair. PARP is immediately activated in response to chemical, metabolic or radiation-induced SSBs. Upon SSB detection, PARP binds the DNA and synthesizes a poly (ADP-ribose) chain (PAR) at the damaged site. The PAR chain then signals the initiation of DNA repair by other enzymes.

This base excision repair mechanism carries a high energy cost, as extensive PARP activation can exhaust cellular NAD+ stores and lead to progressive ATP depletion. Therefore, PARP inactivation occurs in cells with extensive DNA damage, where too much energy would be required to make the necessary repairs. In such cases, a programmed cell death pathway is initiated to conserve energy for other, less damaged cells in the tissue.
