Histones are basic nuclear proteins that are responsible
for the nucleosome structure of the chromosomal fiber in
eukaryotes. This structure consists of approximately 146 bp of DNA
wrapped around a nucleosome, an octamer composed of pairs of each
of the four core histones (H2A, H2B, H3, and H4). The chromatin
fiber is further compacted through the interaction of a linker
histone, H1, with the DNA between the nucleosomes to form higher
order chromatin structures. This gene is intronless and encodes a
member of the histone H3 family. Transcripts from this gene lack
polyA tails; instead, they 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 telomeric copy. [provided by
