Histone H2B
SMART accession number:SM00427
Description: -
Interpro abstract (IPR000558): Histone H2B is one of the four histones, along with H2A, H3 and H4, which forms the eukaryotic nucleosome core. Histone H2B is a small, highly conserved nuclear protein that, together with 2 molecules each of histones H2A, H3 and H4, forms the eukaryotic nucleosome core [(PUBMED:2041803)]; the nucleosome octamer winds ~146 DNA base-pairs.
