Diversity of H2A Histones and Their Effect on Nucleosome Structural Properties Moscow Univ. Biol. Sci. Bull. Pub Date : 2024-02-29
Abstract— Histone proteins that play an important role in the chromatin dynamics and regulation of gene activity are a key epigenetic factor. They are divided into two broad classes: canonical histones and their variants. The canonical histones are expressed mainly during the S phase of the cell cycle, since they are involved in DNA packaging in the process of cell division. The histone variants are
