Chromosome segregation during mitosis requires assembly of the kinetochore complex at the centromere. Kinetochore assembly depends on specific recognition of the histone variant CENP-A in the centromeric nucleosome by centromere protein C (CENP-C). We have defined the determinants of this recognition mechanism and discovered that CENP-C binds a hydrophobic(More)
Chromatin structure and function are regulated by numerous proteins through specific binding to nucleosomes. The structural basis of many of these interactions is unknown, as in the case of the high mobility group nucleosomal (HMGN) protein family that regulates various chromatin functions, including transcription. Here, we report the architecture of the(More)
BACKGROUND The size of organs and tissues is basically determined by the number and size of their cells. However, little attention has been paid to this fundamental concept. The liver has a remarkable ability to regenerate after surgical resection (partial hepatectomy [PHx]), and hepatocytes account for about 80% of liver weight, so we investigate how the(More)
Linker H1 histones facilitate formation of higher-order chromatin structures and play important roles in various cell functions. Despite several decades of effort, the structural basis of how H1 interacts with the nucleosome remains elusive. Here, we investigated Drosophila H1 in complex with the nucleosome, using solution nuclear magnetic resonance(More)
We previously reported the development of an integrated proteome platform, namely 2-Dimensional Image Converted Analysis of Liquid chromatography and mass spectrometry (2DICAL), for quantitative comparison of large peptide datasets generated by nano-flow liquid chromatography (LC) and mass spectrometry (MS). The key technology of 2DICAL was the precise(More)
An efficient method for the production of transgenic papaya was developed via Sonication Assisted Agrobacterium-mediated Transformation (SAAT) of somatic embryos. The plasmid pGA482G was modified to contain gene PTi-Epj-TL-PLDMV with CP coding sequence of PLDMV Japan strain and chimeric gene PTi-NP-YKT with multiple CP coding sequences from PRSV Taiwan(More)
Malus sieboldii Rehd. exhibits high levels of resistance to Valsa canker caused by Valsa ceratosperma (Tode ex Fr.) Maire while cultivated apples (Malus domestica Borkh.) are susceptible to the disease. In this study, progenies from 23 full-sib families derived from both inter- and intra-specific hybridization among 16 Malus genotypes as parents were(More)
Histone tails and their posttranslational modifications play important roles in regulating the structure and dynamics of chromatin. For histone H4, the basic patch K(16)R(17)H(18)R(19) in the N-terminal tail modulates chromatin compaction and nucleosome sliding catalyzed by ATP-dependent ISWI chromatin remodeling enzymes while acetylation of H4 K16 affects(More)
The NMR structure of budding yeast chaperone Chz1 complexed with histones H2A.Z-H2B has been determined. Chz1 forms a long irregular chain capped by two short α-helices, and uses both positively and negatively charged residues to stabilize the histone dimer. A molecular model that docks Chz1 onto the nucleosome has implications for its potential functions.
