UniProt Summary: Acts as a cofactor for serine ADP-ribosylation by conferring serine specificity on PARP1 and PARP2: interacts with PARP1 and PARP1 and is able to change amino acid specificity toward serine (PubMed:28190768). Promotes histone serine ADP- ribosylation in response to DNA damage, limiting DNA damage- induced PARP1 hyper-automodification, and ensuring genome stability (PubMed:27067600, PubMed:28190768). {ECO:0000269|PubMed:27067600, ECO:0000269|PubMed:28190768}.
