Ubiquitination of histone H2B by Rad6 is required for efficient Dot1-mediated methylation of histone H3 lysine 79.

Dot1 is a non-SET domain protein that methylates histone H3 at lysine 79, a surface-exposed residue that lies within the globular domain. In the context of a nucleosome, H3 lysine 79 is located in close proximity with lysine 123 of histone H2B, a major site for ubiquitination by Rad6. Here we show that Rad6-mediated ubiquitination of H2B lysine 123 is important for efficient methylation of lysi...

Thermodynamic Studies on the Interaction of Histone H2B with Dodecyl Trimethyl Ammonium Bromide

The interaction of histone H2B and dodecyl trimethyl ammonium bromide (DTAB) was studies via equilibrium dialysis method at two different temperatures, at pH 6.4 in phosphate buffer. The binding data were used to obtain the Gibbs free energy of interaction, which is interpreted in terms of a theoretical model based on the Wyman binding potential. The data were then used to obtain...

Regulation of histone H2A and H2B deubiquitination and Xenopus development by USP12 and USP46.

Post-translational histone modifications play important roles in regulating gene expression programs, which in turn determine cell fate and lineage commitment during development. One such modification is histone ubiquitination, which primarily targets histone H2A and H2B. Although ubiquitination of H2A and H2B has been generally linked to gene silencing and gene activation, respectively, the fu...

Embryonic regulation of histone ubiquitination in the sea urchin.

We have used quantitative 2-D protein electrophoresis and immunoprecipitation to study the patterns of histone ubiquitination at 10 h and 36 h of embryonic development in Strongylocentrotus purpuratus. Variants csH2A, alpha H2A, beta H2A, gamma H2A, delta HA, H2AF./Z, alpha H2B, beta H2B, and gamma H2B showed up to sevenfold differences in level of monoubiquitination between variants, and indiv...

Histone ubiquitination associates with BRCA1-dependent DNA damage response.

Histone ubiquitination participates in multiple cellular processes, including the DNA damage response. However, the molecular mechanisms involved are not clear. Here, we have identified that RAP80/UIMC1 (ubiquitin interaction motif containing 1), a functional partner of BRCA1, recognizes ubiquitinated histones H2A and H2B. The interaction between RAP80 and ubiquitinated histones H2A and H2B is ...
