Poly (ADP-ribose) polymerase (PARP) is protein family primarily invloved in DNA repair and programmed cell death. PARP proteins are activated in response to DNA single strand breaks (SSBs). Upon SSB detection, PARP binds the DNA and synthesizes a PAR chain at the damaged site, which then signals the initiation of DNA repair by other enzymes such as XRCC1, DNA ligase III and DNA polymerase beta. After repair, the PAR chains are degraded via PAR glycohydrolase.

PARP is inactivated by caspase cleavage, leading to a programmed cell death pathway.

Caspase 3 - a Reliable Marker for Index of Apoptosis Induction
Caspase-3 is one of the most important players in apoptosis signaling. It is synthesized as an inactive 32 kDa pro-enzyme and upon direct activation by Caspase-8, -9 or -10, it gets processed into its active forms, the p17-20 and p10-12 subunits. T...    Read more.
