Summary: 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. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element. This gene is found in a histone cluster on chromosome 1. This gene is one of four histone genes in the cluster that are duplicated; this record represents the centromeric copy. [provided by RefSeq, Aug 2015]

Title: Histone variant H2A.Z modulates nucleosome dynamics to promote DNA accessibility.
Ubiquitin-dependent signaling during the DNA damage response (DDR) to double-strand breaks is initiated by two E3 ligases, RNF8 and RNF168, targeting histone H2A and H2AX. Study shows that ubiquitin chains per se are insufficient for signaling, but RNF168 target ubiquitination is required for DDR damage.
Title: RNF168 ubiquitinates K13-15 on H2A/H2AX to drive DNA damage signaling.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
