Also known as
p06; H3.7; HIST2H3PS2
Histones are basic nuclear proteins responsible for 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 a member of the H3 family, but is found outside of the histone cluster. There is evidence that it is transcribed and has an intact CDS, but residue changes in the protein suggest that it may be on its way to becoming a psuedogene. [provided by RefSeq, Aug 2019]

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.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

  1. NG_012783.2: Suppressed sequence

    NG_012783.2: This RefSeq was removed because it is now thought that this locus is a transcribed gene.
  2. NM_001025303.1: Suppressed sequence

    NM_001025303.1: This RefSeq was permanently suppressed because it is now thought that this gene is a pseudogene.
