  • FunctionInvolved in the base excision repair (BER) pathway, by catalyzing the poly(ADP-ribosyl)ation of a limited number of acceptor proteins involved in chromatin architecture and in DNA metabolism. This modification follows DNA damages and appears as an obligatory step in a detection/signaling pathway leading to the reparation of DNA strand breaks. Mediates the poly(ADP-ribosyl)ation of APLF and CHFR. Positively regulates the transcription of MTUS1 and negatively regulates the transcription of MTUS2/TIP150.
  • Sequence similaritiesContains 1 BRCT domain.
    Contains 1 PARP alpha-helical domain.
    Contains 1 PARP catalytic domain.
    Contains 2 PARP-type zinc fingers.
  • Post-translational
    Phosphorylated by PRKDC. Phosphorylated upon DNA damage, probably by ATM or ATR.
    Poly-ADP-ribosylated by PARP2. Poly-ADP-ribosylation mediates the recruitment of CHD1L to DNA damage sites.
    S-nitrosylated, leading to inhibit transcription regulation activity.

Recombinant Human PARP protein images

  • Lane A: unmodified PARP LANE B: automodified PARP Lane B shows a smear of staining above MW 113kDa indicating polyADP-ribosylated PARP modified to various extents. A significant amount of automodified PARP did not enter the gel (top arrow). This image shows that most of the PARP will be at the top of the gel with a smear running up from 113kDa indicating PARP is automodified to various extents. There is little or no native PARP at 113kDa.
  • All lanes : anti-parp antibody at 5 µg/ml

    Lane 1 : 100ng PARP- unmodified
    Lane 2 : 100ng ab75605 -automodified PARP

    Predicted band size : 113 kDa
    Observed band size : >250 kDa (why is the actual band size different from the predicted?)
