Replication protein A (RPA) is a heterotrimeric, single-strand DNA-binding protein required for DNA metabolism, including DNA replication, repair, and recombination. The physical interaction between the wing motif of human HSF1 and RPA1 was found to provide HSF1 access to nucleosomal DNA, which is important for both basal and inducible gene expression. This access lead to preloading of RNA polymerase II and opened the chromatin structure by recruiting a histone chaperone FACT (Fujimoto M et al. 2012).
