Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a replication-dependent histone that is a member of the histone H2A family. [provided by RefSeq, Aug 2015]
GeneCards Summary for H2AC20 Gene
H2AC20 (H2A Clustered Histone 20) is a Protein Coding gene. Diseases associated with H2AC20 include Riddle Syndrome and Xeroderma Pigmentosum Group E. Among its related pathways are Chromatin organization and Signaling by GPCR. An important paralog of this gene is H2AC18.
UniProtKB/Swiss-Prot Summary for H2AC20 Gene
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.
