CIA, an interactor of the CCG1 histone acetyltransferase subunit of TFIID, was identified as a human histone chaperone. The Saccharomyces cerevisiae orthologue ASF1, when it was over-expressed, was reported to cause de-repression of silent loci; however, the involvement of Asf1p in the alteration of nucleosomal structures remained unknown. Curiously, there is a polyanionic stretch, a structural motif characteristic of histone chaperones, in S. cerevisiae Asf1p, but not in human CIA. We investigated how CIA/Asf1p utilizes its domain(s) for the alteration of nucleosomal structure.
