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].

CENP-T is a family of vertebral kinetochore proteins that associates directly with CENP-W. The N-terminus of CENP-T proteins interacts directly with the Ndc80 complex in the outer kinetochore. Importantly, the CENP-T-W complex does not directly associate with CENP-A, but with histone H3 in the centromere region. CENP-T and -W form a hetero-tetramer with CENP-S and -X and bind to a ~100 bp region of nucleosome-free DNA forming a nucleosome-like structure. The DNA-CENP-T-W-S-X complex is likely to be associated with histone H3-containing nucleosomes rather than with CENP-nucleosomes. This domain is the C-terminal histone fold domain of CENP-T, which associates with chromatin [2-3].

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].

This domain is found in a variety of polyA polymerases as well as the E. coli molybdate metabolism regulator Swiss:P33345 and other proteins of unknown function. I have called this domain WGR after the most conserved central motif of the domain. The domain is found in isolation in proteins such as Swiss:Q9JN21 and is between 70 and 80 residues in length. I propose that this may be a nucleic acid binding domain.
