Several studies indicate that H2A.Z is found at specific loci in the genome such as regulatory-gene regions, where it poises genes for transcription.
WebbThe diversity of histone variants results in structural plasticity of chromatin and highlights functionally distinct chromosomal domain, which plays critical roles in development from a fertilized egg into a complex organism, as well as in aging and diseases. However, the mechanisms of this fundamental process are poorly understood so far. Webb13 sep. 2009 · Epigenetic mechanisms that modify chromatin structure can be divided into four main categories: DNA methylation, covalent histone modifications, non-covalent mechanisms such as incorporation of histone variants and nucleosome remodeling and non-coding RNAs including microRNAs (miRNAs).
