Transcription factor that acts synergistically with SOX11 and SOX4. Plays a role in neuronal development. Is implicated in an enhancer activity at the embryonic met-mesencephalic junction; the enhancer element contains the octamer motif (5'-ATTTGCAT-3') (By similarity).
Interacting selectively and non-covalently with an HMG box domain, a protein domain that consists of three helices in an irregular array. HMG-box domains are found in one or more copies in HMG-box proteins, which form a large, diverse family involved in the regulation of DNA-dependent processes such as transcription, replication, and strand repair, all of which require the bending and unwinding of chromatin.
Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.

Sequence-specific DNA binding transcription factor activitydefinition[GO:0003700]‹silver
Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
The process whose specific outcome is the progression of the central nervous system over time, from its formation to the mature structure. The central nervous system is the core nervous system that serves an integrating and coordinating function. In vertebrates it consists of the brain, spinal cord and spinal nerves. In those invertebrates with a central nervous system it typically consists of a brain, cerebral ganglia and a nerve cord.
The class III POU transcription factor genes play an important role in the nervous system. Comparison of their entire amino acid sequences disclosed a remarkable feature of particular mammalian class III POU genes. Alanine, glycine, and proline repeats were present in the mammalian Brain-1 gene, whereas most of these repeats were absent in the nonmammalian homologue. The mammalian Brain-2 gene had alanine, glycine, proline, and glutamine repeats, which were missing in the nonmammalian homologue. The mammalian Scip gene had alanine, glycine, proline, and histidine repeats, but the nonmammalian homologue completely lacked these repeats. In contrast, the mammalian Brain-4 gene had no amino acid repeats like its nonmammalian homologue. The mammalian genes containing the characteristic amino acid repeats had another feature, higher GC content. We found a positive correlation between the GC content and the amino acid repeat ratio. Those amino acids were encoded by triplet codons with relatively high GC content. These results suggest that the GC pressure has facilitated generation of the homopolymeric amino acid repeats.
The migration of cells in the developing cerebral cortex in which cells move from the ventricular and/or subventricular zone toward the surface of the brain.
The process whose specific outcome is the progression of a metanephric ascending thin limb over time, from its formation to the mature structure. The metanephric ascending thin limb is a segment of a nephron tubule in the metanephros lying in the inner medulla that is permeable to ions but not to water and has a simple epithelium; active transepithelial solute transport is absent.
The process in which relatively unspecialized cells acquire specialized structural and/or functional features that characterize the distal convoluted tubule cells of the metanephros as it progresses from its formation to the mature state.
The process whose specific outcome is the progression of the metanephric loop of Henle over time, from its formation to the mature structure. The metanephric loop of Henle is a metanephric nephron tubule that connects the proximal convoluted tubule to the distal convoluted tubule in the metanephros.
The process whose specific outcome is the progression of the metanephric macula densa over time, from its formation to the mature structure. The metanephric macula densa is an area of specialized cells in the distal tubule of the metanephros that makes contact with the vascular pole of the glomerulus.
The process whose specific outcome is the progression of the metanephric thick ascending limb over time, from its formation to the mature structure. The metanephric thick ascending limb is the last part of the metanephric loop of Henle. Its thick, mitochondria-rich epithelium characterizes the outer medulla, and is responsible for very avid active salt transport. At the macula densa, the thick ascending limb connects to the distal convoluted tubule.
Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Some protein processing events may be included when they are required to form an active form of a product from an inactive precursor form.

Positive regulation of transcription from RNA polymerase II promoterdefinition[GO:0045944]‹silver
Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
Protein involved in the transfer of genetic information from DNA to messenger RNA (mRNA) by DNA-directed RNA polymerase. In the case of some RNA viruses, protein involved in the transfer of genetic information from RNA to messenger RNA (mRNA) by RNA-directed RNA polymerase.
Protein involved in development, the process whereby a multicellular organism develops from its early immature forms, e.g., zygote, larva, embryo, into an adult.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
