CC   -!- FUNCTION: DNA-binding protein that induces severe bending of DNA.
CC       Required for DNA-binding by the FACT complex, a general chromatin
CC       factor that acts to reorganize nucleosomes. The FACT complex is
CC       involved in multiple processes that require DNA as a template such as
CC       mRNA elongation, DNA replication and DNA repair (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Probably associates with the stable spt16-ssrp1 heterodimer to
CC       form the FACT complex. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00267}.
CC       Chromosome {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the NHP6 family. {ECO:0000305}.
