Nucleosome-destabilizing factor that is recruited to genes during transcriptional activation and colocalizes with a subset of trimethylated 'Lys-36' histone H3 (H3K36me3)-enriched regions. Binds to mononucleosomes. The PWWP domain is a H3 reader and strongly binds DNA. In the dehydrogenase domain, the conserved NAD(P)H-binding sites and sequence similarity to plant dehydrogenases suggest that this protein may have oxidoreductase activity. However, since the active site is not conserved, the dehydrogenase domain seems to serve as a catalytically inert oligomerization module. Belongs to the HIBADH-related family. NP60 subfamily.
