Target

  • Function

    Involved 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 similarities

    Contains 1 BRCT domain.
    Contains 1 PARP alpha-helical domain.
    Contains 1 PARP catalytic domain.
    Contains 2 PARP-type zinc fingers.
  • Post-translational
    modifications

    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.

    Lanes 1 - 4: Merged signal (red and green). Green - ab191217 observed at 125 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab191217 was shown to specifically react with PARP1 when PARP1 knockout samples were used. Wild-type and PARP1 knockout samples were subjected to SDS-PAGE. ab191217 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
