Serine ADP-ribosylation depends on HPF1


ABSTRACT: We report that serine ADPr is strictly dependent on HPF1 (histone PARylation factor 1. Quantitative proteomics revealed that serine ADPr does not occur in cells lacking HPF1. We identified three endogenous serine ADPr sites are located on the PARP-1 automodification domain. Further identification of serine ADPr on hundreds of other targets indicates that serine ADPr is a widespread modification.

ADP-ribosylation (ADPr) regulates important patho-physiological processes through its attachment to different amino acids in proteins. Recently, by precision mapping on all possible amino acid residues, we identified histone serine ADPr marks in the DNA damage response. However, the biochemical basis underlying this serine modification remained unknown. Here we report that serine ADPr is strictly dependent on histone PARylation factor 1 (HPF1), a recently identified regulator of PARP-1. Quantita  ...[more]
