General annotation (Comments)

Function	Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facilitates the passage of RNA polymerase II and transcription by promoting the dissociation of one histone H2A-H2B dimer from the nucleosome, then subsequently promotes the reestablishment of the nucleosome following the passage of RNA polymerase II. Binds specifically to double-stranded DNA By similarity.
Subunit structure	Component of the FACT complex, a stable heterodimer of SPT16 and SSRP1 By similarity.
Subcellular location	Nucleus By similarity.
Sequence similarities	Belongs to the SSRP1 family. Contains 1 HMG box DNA-binding domain.
