Human Asf1 and CAF-1 interact and synergize in a repair-coupled nucleosome assembly pathway.

The efficient assembly of newly replicated and repaired DNA into chromatin is essential for proper genome function. Based on genetic studies in Saccharomyces cerevisiae, the histone chaperone anti-silencing function 1 (Asf1) has been implicated in the DNA repair response. Here, the human homologs are shown to function synergistically with human CAF-1 to assemble nucleosomes during nucleotide excision repair in vitro.
