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 Name=3;
CC IsoId=Q9DCB1-3; Sequence=VSP_017911, VSP_017912;
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}.
