The histone chaperone FACT plays an important role in facilitating nucleosome assembly and disassembly during transcription. FACT is a heterodimeric complex consisting of Spt16 and SSRP1. The N-terminal domain of Spt16 resembles an inactive aminopeptidase. How this domain contributes to the histone chaperone activity of FACT remains elusive. Here, the crystal structure of the N-terminal domain (NTD) of human Spt16 is reported at a resolution of 1.84 Å. The structure adopts an aminopeptidase-like fold similar to those of theSaccharomyces cerevisiaeandSchizosaccharomyces pombeSpt16 NTDs. Isothermal titration calorimetry analyses show that human Spt16 NTD binds histones H3/H4 with low-micromolar affinity, suggesting that Spt16 NTD may contribute to histone binding in the FACT complex. Surface-residue conservation and electrostatic analysis reveal a conserved acidic patch that may be involved in histone binding.

AbstractTIP60 consists of an N-terminal chromo barrel domain (TIP60-CB) and a C-terminal acetyltransferase domain and acetylates histone and non-histone proteins within diverse cellular processes. Whereas the TIP60-CB is thought to recognize histone tails, molecular details of this interaction remain unclear. Here we attempted a quantitative analysis of the interaction between the TIP60-CB and histone peptides, but did not observe any binding through either fluorescence polarization or isothermal titration calorimetry. We solved a crystal structure of the TIP60-CB alone. Analysis of the crystal structure demonstrates a putative peptide binding site that may be occluded by the basic side chain of a residue in a unique β hairpin between the two N-terminal strands of the β barrel.
