The human protein, encoded by the gene HIST1H1B, is a member of the Histone H1/H5 family. The protein's cellular localization is indicated to be nuclear. Additional synonyms or past names for this protein may include: H1, H1.5, H1B, H1F5, H1s-3. Homology is conserved in other species, such as Mouse, Rat, Frog.
