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.
