Summary

Go to the top of the page Help

Gene symbol: HTA9
Gene description: histone H2A protein 9
Primary source: Araport:AT1G52740
Locus tag: AT1G52740
See related: TAIR:AT1G52740
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F14G24.1; F14G24_1; histone H2A protein 9
Summary: Encodes HTA9, a histone H2A protein. Loss of all H2A.Z (triple mutant with HTA8 and HTA11) results in a reduction in DNA methylation of transposons but not that of genes. Loss of H2A.Z causes misregulation of many genes involved in the response to developmental and environmental cues, and that these genes tend to have high levels of gene-body H2A.Z.

Data suggests an antagonistic role between H2A.Z and H3K4me3 in the regulation of the expression of anthocyanin biosynthetic genes, highlighting a role of chromatin in gene regulation and reflecting the complexity of gene regulatory mechanisms.s [H2A.Z] [HTA9]

YAF9A binds FLC chromatin and that YAF9 proteins regulate FLC expression by modulating the acetylation levels of H2A.Z and H4 but not H2A.Z deposition.[H2A.z]
Title: Arabidopsis YAF9 histone readers modulate flowering time through NuA4-complex-dependent H4 and H2A.Z histone acetylation at FLC chromatin.
MBD9 is a SWR1-C interacting protein required for H2A.Z deposition at a subset of actively transcribing genes. [H2A.Z]

H2A.z mediates different aspects of chromatin function. Gene expression changes in plant responsiveness to environmental cues also involve H2A.Z, in particular in temperature sensing and in the flowering response to ambient temperature. [H2A.Z]
Title: H2A.Z mediates different aspects of chromatin function and modulates flowering responses in Arabidopsis.
The induction of ethylene-responsive genes does not require immediate modulation of H3K4me3 and H3K27me3 and dissociation of LHP1 and H2A.Z from the targets.[H2A.Z]
