Histones are basic nuclear proteins that are responsible
for the nucleosome structure of the chromosomal fiber in
eukaryotes. Nucleosomes consist of approximately 146 bp of DNA
wrapped around a histone 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
testis/sperm-specific member of the histone H2B family. Transcripts
from this gene contain a palindromic termination element. [provided
