The histone domain of macroH2A1 is alone sufficient to direct enrichment on the inactive X chromosome when expressed in female cells, indicating that sequences important for correct localization ysf in this domain.
Nat Rev Mol Cell Biol 8: Histone variant macroH2A contains two distinct macrochromatin domains capable of directing macroH2A to the inactive X chromosome.
Seeded strain-like transmission of β-amyloid morphotypes in APP transgenic mice
The red line and blue line below the sequence indicates the 22007 of the mH2A1-HD incorporated into the chimeras. Author information Article notes Copyright and License information Disclaimer.
Next, we asked whether individual amino acids of mH2A1-HD were sufficient to direct enrichment on the Xi. Nearly all of the core histones have variants, with histone H2A showing the greatest diversity in metazoans. Source data for Supplementary Figures K, pdf. These data indicate that localization function pk been evolutionarily conserved in the regions that have diverged between these two macroH2A family members.
National Center for Biotechnology InformationU.
Mapping post-translational modifications of the histone variant MacroH2A1 using tandem mass spectrometry. Here we investigate whether divergent sequences of the H2A variant macroH2A1 contribute to its correct localization. Source data for Figure 2 31K, pdf. Phylogenomics of the nucleosome. These ,p suggest that in some instances a single amino acid may be sufficient to determine which loader or exchange factor H2A or macroH2A1 interacts with, while in other jse the interaction face may be more extended.
Developmentally regulated alterations in Polycomb repressive complex 1 proteins on the inactive X chromosome. As a service to our customers we are providing this early version of the manuscript. Crystal structure of a nucleosome core particle containing the variant histone H2A. Residues that induced Xi-enrichment are colored ip and residues that did not are colored yellow. MacroH2A variants consist of an N-terminal histone domain and a large C-terminal macro domain.

The dotted line indicates a ratio of 1. Chakravarthy S, Luger K.
Proper localization of histone variants yee distinct regions of the genome is critical for their function, yet how this specific localization is achieved remains unclear. Pericentric heterochromatin yde enriched with H2A. The proportion of transfected cells with Xi-enrichment was determined for each construct Figure 2.
We would also like to thank Brian Kelch for help with crystal structure analysis. This is a PDF file of an unedited manuscript that has been accepted for publication. Histone H2A variants and the inactive X chromosome: Immunoblotting of Laser-Dissected Tissue. The authors declare that they have no conflict of interest.
H2A and H2A variants exhibit considerable sequence conservation; however, the regions in similar positions to those of mH2A1-HD that promoted Xi-enrichment Supplemental Figure 1indicated by a red box and those that did not Supplemental Figure 1indicated by a yellow box show considerable variability between variants.
