CC   -!- FUNCTION: Binds and compact DNA (95 to 150 base pairs) to form
CC       nucleosome-like structures that contain positive DNA supercoils.
CC       Increases the resistance of DNA to thermal denaturation (in vitro).
CC       {ECO:0000250|UniProtKB:P19267}.
CC   -!- SUBUNIT: Homodimer or heterodimer with another histone. Dimers then
CC       assemble into higher oligomers, with the DNA wrapped around the protein
CC       core (By similarity). {ECO:0000250|UniProtKB:P19267}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}. Chromosome
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the archaeal histone HMF family. {ECO:0000305}.
