Monoubiquitination of histone H2B blocks eviction of histone variant H2A.Z from inducible enhancers.
Thus, PWWP2A is a novel H2A.Z-specific multivalent chromatin binder providing a surprising link between H2A.Z, chromosome segregation, and organ development.
SMYD3 (zeige SMYD3 ELISA Kits)-mediated H2A.Z.1K101 dimethylation activates cyclin A1 (zeige CCNA1 ELISA Kits) expression and contributes to driving the proliferation of breast cancer cells.
Results suggest that the N-terminal tail of H2A.Z makes distinctively different contributions to epigenetic events.
the H2AFZ gene may confer a risk for schizophrenia and contribute to the impairment of executive function in Han Chinese patients with schizophrenia.
The 2.7-A-resolution crystal structure of the human YL1 (zeige VPS72 ELISA Kits)-H2A.Z-H2B complex shows that YL1 (zeige VPS72 ELISA Kits) binding, similarly to ANP32E (zeige ANP32E ELISA Kits) binding, triggers an extension of the H2A.Z alphaC helix.
H2A.Z removal from chromatin is the primary function of INO80 (zeige INO80 ELISA Kits) and ANP32E (zeige ANP32E ELISA Kits) in promoting homologous recombination.
Results demonstrated male-selective association of the H2AFZ gene with schizophrenia, and that modification of the H2AFZ signaling pathway warrants further study in terms of the pathophysiology of schizophrenia
Dynamic modulation of H2A.Z exchange and removal by Anp32e (zeige ANP32E ELISA Kits) reveals the importance of the nucleosome surface and nucleosome dynamics in processing the damaged chromatin template during DSB repair.
The findings implicate H2A.Z.2 as a mediator of cell proliferation and drug sensitivity in malignant melanoma.
This study reveals an antagonistic relationship between H2A.Z.1ub and BRD2 (zeige BRD2 ELISA Kits) to regulate the transcriptional balance at bivalent genes to enable proper execution of developmental programs.
Embryonic stem cell BAF (zeige BANF1 ELISA Kits) is required for normal H2A.Z localization in these cells, suggesting BAF (zeige BANF1 ELISA Kits) either stabilizes H2A.Z containing nucleosomes or promotes subnucleosome to nucleosome conversion by facilitating H2A.Z deposition.
Study mapped H2A.Z genome-wide in embryonic stem cells and neural progenitors; H2A.Z is deposited at promoters and enhancers, and correlates strongly with H3K4 methylation. H2A.Z is present at poised promoters with bivalent chromatin and at active promoters with H3K4 methylation, but is absent from stably repressed promoters that are enriched for H3K27 trimethylation.
our work suggests that the divergent residues in the H2A.Z acidic patch comprise a unique domain that couples control of chromatin dynamics to the regulation of developmental gene expression patterns during lineage commitment.
Data propose that H2A.Z mediates such contrasting activities by acting as a general facilitator that generates access for a variety of complexes, both activating and repressive.
The variant histone H2A.Z and the winged helix transcription factor (zeige FOXC1 ELISA Kits) Foxa2 (zeige FOXA2 ELISA Kits) both act to regulate nucleosome depletion and gene activation, thus promoting embryonic stem cell differentiation, whereas DNA methylation (zeige HELLS ELISA Kits) promotes nucleosome occupation and suppresses gene expression.
incorporation of the histone variant H2A.Z at the promoter regions of PPARgamma (zeige PPARG ELISA Kits) target genes by p400 (zeige ITPR1 ELISA Kits)/Brd8 (zeige BRD8 ELISA Kits) is essential to allow fat cell differentiation
In mouse trophoblast stem cells, the amount of histone H2A.Z at promoters decreased during S phase, coinciding with homotypic (H2A.Z-H2A.Z) nucleosomes flanking the TSS (zeige RPL38 ELISA Kits) becoming heterotypic (H2A.Z-H2A).
It was shown that Ring1B (zeige RNF2 ELISA Kits) interacted with multiple complexes in embryonic stem cells. Although H2A.Z co-localized with Eed (zeige EED ELISA Kits), Ring1B (zeige RNF2 ELISA Kits) and CpG islands in chromatin, H2A.Z still blanketed polycomb (zeige CBX2 ELISA Kits) target loci in the absence of Suz12 (zeige SUZ12 ELISA Kits), Eed (zeige EED ELISA Kits), or Ring1B (zeige RNF2 ELISA Kits).
Studies indicate that the unique chromatin landscape also includes a second histone variant, H2A.Z.
Depletion of H2A.Z by RNA interference perturbs Xenopus laevis development at gastrulation leading to embryos with malformed, shortened trunks.
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. This gene encodes a replication-independent member of the histone H2A family that is distinct from other members of the family. Studies in mice have shown that this particular histone is required for embryonic development and indicate that lack of functional histone H2A leads to embryonic lethality.
