General processes & autonomous pathway

Protein function

Encodes a histone H2A.Z variant protein.

Phenotype

Multiple mutant:
hta9;hta11 multiple mutant is early flowering under both SD and LD conditions. [Coleman-Derr et al., 2012]

Function:
Variant histones H2A are synthesized throughout the cell cycle and are very different from classical S-phase regulated H2A. May replace conventional H2A in a subset of nucleosomes. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling (By similarity). [Data from UniProt]
