  ABSTRACT  
 
CIA (CCG1-interacting factor A)/ASF1, which is the most conserved histone chaperone among the eukaryotes, was genetically identified as a factor for an anti-silencing function (Asf1) by yeast genetic screening. Shortly after that, the CIA-histone-H3-H4 complex was isolated from Drosophila as a histone chaperone CAF-1 stimulator. Human CIA-I/II (ASF1a/b) was identified as a histone chaperone that interacts with the bromodomain-an acetylated-histone-recognizing domain-of CCG1, in the general transcription initiation factor TFIID. Intensive studies have revealed that CIA/ASF1 mediates nucleosome assembly by forming a complex with another histone chaperone in human cells and yeast, and is involved in DNA replication, transcription, DNA repair and silencing/anti-silencing in yeast. CIA/ASF1 was shown as a major storage chaperone for soluble histones in proliferating human cells. Despite all these biochemical and biological functional analyses, the structure-function relationship of the nucleosome assembly/disassembly activity of CIA/ASF1 has remained elusive. Here we report the crystal structure, at 2.7 A resolution, of CIA-I in complex with histones H3 and H4. The structure shows the histone H3-H4 dimer's mutually exclusive interactions with another histone H3-H4 dimer and CIA-I. The carboxy-terminal beta-strand of histone H4 changes its partner from the beta-strand in histone H2A to that of CIA-I through large conformational change. In vitro functional analysis demonstrated that CIA-I has a histone H3-H4 tetramer-disrupting activity. Mutants with weak histone H3-H4 dimer binding activity showed critical functional effects on cellular processes related to transcription. The histone H3-H4 tetramer-disrupting activity of CIA/ASF1 and the crystal structure of the CIA/ASF1-histone-H3-H4 dimer complex should give insights into mechanisms of both nucleosome assembly/disassembly and nucleosome semi-conservative replication.

Figure 1: Overall structure and biochemical analysis of the CIA-I–histone-H3–H4 complex. a, The overall structure of the CIA-I–histone-H3–H4 complex. CIA-I and histones H3 and H4 are shown in red, blue, and green, respectively. An orange triangle indicates the HIRA (histone regulatory homologue A) binding site^28. The molecular graphics were prepared by PyMOL^29. b, Possible modification sites (stick model in orange) and the different residues of human histone H3.1 and H3.3 in the CIA-I–histone-H3–H4 complex (sphere model in pink, only exposed residues are displayed). c, The histone H3–H3' interaction in the nucleosome core^21. d, CIA-I–histone H3 interaction in the CIA-I–histone-H3–H4 complex. e, Carboxy-terminal residues (Thr 96–Tyr 98) of histone H4 (green) form a parallel -sheet with a -strand from H2A (yellow) in the nucleosome core^21. f, The C-terminal fragment of histone H4 undergoes a conformational change on the CIA-I–histone-H3–H4 complex formation through rotations of main-chain angles of Gly 94 and Arg 95 by 95° and 75°, respectively. Histone H4s in the present structure and the nucleosome core are shown in green and light green, respectively. This conformational change and formation of a new anti-parallel -sheet might facilitate the histone H3–H4 tetramer-disruption. The large effect (tetramer disruption) originating from a small interaction (formation of -sheet) is similar to the essence of Japanese Judo (Yawara): 'softness tames toughness (ju yoku go wo seisu)'. Following the spirit of Judo, we designated the mechanism as the 'Yawara split'. It is intriguing to note that most histone chaperones have a -rich structure. g, Pull-down assay with GST-tagged human CIA-I(155) or GST (control), showing the stoichiometric interaction between CIA and the histone H3–H4 complex. h, Determination of the molecular weight of human CIA, histone dimer, tetramer, and complexes by the static light-scattering method. LS and RI represent the intensity of static light scattering and the refractive index, respectively.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
