Histone PARylation factor 1 (HPF1, previously known as C4orf27) is a key regulator of ADP-ribosylation (ADPr) signaling in response to DNA damage. It forms a complex with PARP-1 (poly(ADP-ribose) polymerase 1), creating a composite active site. HPF1 is essential for Ser-ADPr (ADPr on serine residues), which represents the major fraction of ADPr synthesised after DNA damage. This protein is organised into two tightly-associated domains connected via an elaborate linker, showing an alpha-beta structure [1-4].	Domain

Poly(ADP-ribose) polymerase catalyses the covalent attachment of ADP-ribose units from NAD+ to itself and to a limited number of other DNA binding proteins, which decreases their affinity for DNA. Poly(ADP-ribose) polymerase is a regulatory component induced by DNA damage. The carboxyl-terminal region is the most highly conserved region of the protein. Experiments have shown that a carboxyl 40 kDa fragment is still catalytically active [2].	Domain
