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 encodes a member of the histone H2B family,
and generates two transcripts through the use of the conserved
stem-loop termination motif, and the polyA addition motif.
