CC -!- FUNCTION: Component of the FACT complex, a general chromatin factor
CC that acts to reorganize nucleosomes. The FACT complex is involved in
CC multiple processes that require DNA as a template such as mRNA
CC elongation, DNA replication and DNA repair. During transcription
CC elongation the FACT complex acts as a histone chaperone that both
CC destabilizes and restores nucleosomal structure. It facilitates the
CC passage of RNA polymerase II and transcription by promoting the
CC dissociation of one histone H2A-H2B dimer from the nucleosome, then
CC subsequently promotes the reestablishment of the nucleosome following
CC the passage of RNA polymerase II. {ECO:0000256|RuleBase:RU364013}.
CC -!- SUBUNIT: Component of the FACT complex, a stable heterodimer of SPT16
CC and SSRP1. {ECO:0000256|ARBA:ARBA00011111}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|RuleBase:RU364013}.
CC Chromosome {ECO:0000256|RuleBase:RU364013}.
CC -!- SIMILARITY: Belongs to the SSRP1 family.
