| [[http://www.uniprot.org/uniprot/H2A1_XENLA H2A1_XENLA]] Core component of nucleosome. 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. [[http://www.uniprot.org/uniprot/DOT1L_HUMAN DOT1L_HUMAN]] Histone methyltransferase. Methylates 'Lys-79' of histone H3. Nucleosomes are preferred as substrate compared to free histones. Binds to DNA. [[http://www.uniprot.org/uniprot/H4_XENLA H4_XENLA]] Core component of nucleosome.
