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:0000269|PubMed:12185205,

CC       ECO:0000269|PubMed:19651901, ECO:0000269|PubMed:19885867}.
CC   -!- SUBUNIT: Interacts with the ligand binding domain of the thyroid
CC       receptor (TR) (in vitro). Requires the presence of thyroid hormone for
CC       its interaction. Interacts with transcriptional regulator SEHBP.
CC       Interacts with nucleosomes. {ECO:0000250|UniProtKB:Q15651}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.

CC   -!- TISSUE SPECIFICITY: Expressed in the brain, eye, prostate, thyroid,
CC       kidney, testis, glial cells and insulin-producing cells of the
CC       Langerhans pancreatic islets. In the brain, expressed in the lateral
CC       olfactory tract, anterior commissure, corpus callosum, internal
CC       capsule, fornix, stria medullans, optic tract, axon bundles, Purkinje
CC       cell layer and granular layer of the cerebellum. In retina, expressed
CC       in the nuclei of cells in the inner nuclear layer including amacrine,
CC       bipolar and horizontal neurons and in the nuclei of ganglion neurons.
CC       Detected at low levels in the liver. {ECO:0000269|PubMed:11356838,
CC       ECO:0000269|PubMed:12185205, ECO:0000269|PubMed:15082770,

CC       ECO:0000269|PubMed:19885867}.
CC   -!- DEVELOPMENTAL STAGE: Transiently expressed in the stroma and
CC       endothelium of the cornea at birth. Subsequently expressed in the
CC       corneal epithelium and the inner nuclear and ganglion cell layers of
CC       the retina. The predominant form in developing ocular tissues is
CC       isoform 2, although isoform 1 is also detectable.
CC       {ECO:0000269|PubMed:18502697}.
CC   -!- DISRUPTION PHENOTYPE: Mice are viable and fertile. Mice have a mild
CC       diabetic phenotype and lower plasma glucagon levels. The overall shape
CC       of the islets, the location of the alpha cells in the mantle of the
CC       pancreatic islets or proliferation of pancreatic alpha cells are not
CC       affected. {ECO:0000269|PubMed:19651901, ECO:0000269|PubMed:19885867}.
CC   -!- SIMILARITY: Belongs to the HMGN family. {ECO:0000305}.
