Descripción

General description

Histone H2B is one of four core histones that form an octameric structure required for the packaging of DNA into nucleosomes, the most basic level of chromatin arrangement. Histones undergo a number of post-translational modifications (PTM) at their N- and C-terminal tails which can influence chromatin structure and stability and consequently, transcription, and DNA replication and repair. The most widely studied of these modifications are methylation, phosphorylation, and acetylation which may produce different effects on gene regulation depending on the number and pattern of modifications. Histone H2B undergoes acetylation at lysines 5, 15, and 20. It is also phosphorylated in apoptotic cells during DNA fragmentation, possibly in a caspase-dependent manner.
