Reconstitution of mitotic chromatids with a minimum set of purified factors.
Wako, Japan. In Nat Cell Biol, 15 Jul 2015
We find that octameric nucleosomes containing the embryonic variant H2A.X-F are highly susceptible to FACT and function as the most productive substrate for subsequent actions of topo II and condensin I. Cdk1 phosphorylation of condensin I is the sole mitosis-specific modification required for chromatid reconstitution.
Development of cancer-initiating cells and immortalized cells with genomic instability.
Tokyo, Japan. In World J Stem Cells, Apr 2015
We summarize recently established knowledge of CIC development and cellular immortality, explore the role of the ARF/p53 module in protecting cells from transformation, and describe a risk factor for genomic destabilization that increases during the process of normal cell growth and differentiation and is associated with the downregulation of histone H2AX to levels representative of growth arrest in normal cells.
The Structural Determinants behind the Epigenetic Role of Histone Variants.
Victoria, Canada. In Genes (basel), Dec 2014
A picture starts to emerge in which histone H2A variants, in addition to their individual specific contributions to the nucleosome structure and dynamics, globally impair the accessibility of linker histones to defined chromatin locations and may have important consequences for determining different states of chromatin metabolism.
RNF168 ubiquitinates K13-15 on H2A/H2AX to drive DNA damage signaling.

Amsterdam, Netherlands. In Cell, 2012
Ubiquitin-dependent signaling during the DNA damage response (DDR) to double-strand breaks is initiated by two E3 ligases, RNF8 and RNF168, targeting histone H2A and H2AX. Study shows that ubiquitin chains per se are insufficient for signaling, but RNF168 target ubiquitination is required for DDR damage.
