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. Promotes histone serine ADP-ribosylation in response to DNA damage, limiting DNA damage-induced PARP1 hyper-automodification, and ensuring genome stability. Full length recombinant protein corresponding to aa1-346 of human Histone PARylation Factor 1, fused to 10X His-Sumo-Tag at N-terminal and Myc-Tag at C-terminal, expressed in E. coli (Q9NWY4).
