CC   -!- FUNCTION: Histones H1 are necessary for the condensation of nucleosome
CC       chains into higher-order structures. The histones H1.0 are found in
CC       cells that are in terminal stages of differentiation or that have low
CC       rates of cell division (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus. Chromosome.
CC   -!- SIMILARITY: Belongs to the histone H1/H5 family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00837}.
