  • Post Translation Modifications
  • Poly-ADP-ribosylated on serine, glutamate and aspartate residues by autocatalysis (PubMed:19764761, PubMed:20388712, PubMed:22582261).
    Auto-ADP-ribosylation on serine takes place following interaction with HPF1 (PubMed:28190768, PubMed:34625544).
    Auto poly-ADP-ribosylation on serine residues promotes its dissociation from chromatin (PubMed:15607977, PubMed:30675909, PubMed:32358582, PubMed:34210965, PubMed:34625544).
    Poly-ADP-ribosylated by PARP2; poly-ADP-ribosylation mediates the recruitment of CHD1L to DNA damage sites (PubMed:19661379).
    Mono-ADP-ribosylated at Lys-521 by SIRT6 in response to oxidative stress, promoting recruitment to double-strand breaks (DSBs) sites (PubMed:21680843, PubMed:22753495, PubMed:27568560).
    Phosphorylated at Thr-594 by PRKDC in response to DNA damage following virus infection, promoting its translocation to the cytosol (PubMed:10467406, PubMed:35460603).
    Phosphorylated by TXK (PubMed:17177976).
    S-nitrosylated, leading to inhibit transcription regulation activity.
    Proteolytically cleaved by caspase-3 (CASP3) and caspase-7 (CASP7) in response to apoptosis to generate the Poly [ADP-ribose] polymerase 1, processed N-terminus and Poly [ADP-ribose] polymerase 1, processed C-terminus forms (PubMed:7596430, PubMed:10497198, PubMed:16374543, PubMed:22464733, PubMed:22451931, PubMed:33168626, PubMed:35104452).
    CASP3-mediated cleavage is promoted by the TP53/p53-induced long non-coding RNA SPARCLE, which binds PARP1 in response to genotoxic stress (PubMed:35104452).
    Sumoylated with SUMO1 or SUMO2 by PIAS4 following prolonged residence (trapping) to chromatin (PubMed:35013556).
    Sumoylation promotes ubiquitination by RNF4 and removal from chromatin by VCP/p97 (PubMed:35013556).
    Ubiquitinated by RNF4 following sumoylation by PIAS4 in response to prolonged residence (trapping) to chromatin (PubMed:35013556).
    Ubiquitination promotes removal from chromatin by VCP/p97 (PubMed:35013556).
  • Function
  • Poly-ADP-ribosyltransferase that mediates poly-ADP-ribosylation of proteins and plays a key role in DNA repair. Mediates glutamate, aspartate, serine, histidine or tyrosine ADP-ribosylation of proteins: the ADP-D-ribosyl group of NAD+ is transferred to the acceptor carboxyl group of target residues and further ADP-ribosyl groups are transferred to the 2'-position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units. Serine ADP-ribosylation of proteins constitutes the primary form of ADP-ribosylation of proteins in response to DNA damage. Following interaction with HPF1, catalyzes serine ADP-ribosylation of target proteins; HPF1 confers serine specificity by completing the PARP1 active site. Also catalyzes tyrosine ADP-ribosylation of target proteins following interaction with HPF1. Following interaction with NMNAT1, catalyzes glutamate and aspartate ADP-ribosylation of target proteins; NMNAT1 confers glutamate and aspartate specificity.
