CC   -!- FUNCTION: Binds to nucleosomes, regulating chromatin structure and
CC       consequently, chromatin-dependent processes such as transcription, DNA
CC       replication and DNA repair. Affects both insulin and glucagon levels
CC       and modulates the expression of pancreatic genes involved in insulin
CC       secretion. Regulates the expression of the glucose transporter SLC2A2
CC       by binding specifically to its promoter region and recruiting PDX1 and
CC       additional transcription factors. Regulates the expression of SLC6A9, a
CC       glycine transporter which regulates the glycine concentration in
CC       synaptic junctions in the central nervous system, by binding to its
CC       transcription start site. May play a role in ocular development and
CC       astrocyte function. {ECO:0000256|ARBA:ARBA00025168}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123}.
CC   -!- SIMILARITY: Belongs to the HMGN family.
CC       {ECO:0000256|ARBA:ARBA00007696}.
