UniProtKB description: Scaffold protein involved in DNA single-strand break repair by mediating the assembly of DNA break repair protein complexes (By similarity). Negatively regulates ADP-ribosyltransferase activity of PARP1 during base-excision repair in order to prevent excessive PARP1 activity (PubMed:28002403). Recognizes and binds poly-ADP-ribose chains: specifically binds auto-poly-ADP-ribosylated PARP1, limiting its activity (By similarity).
