ID:OLIG2_MOUSE DESCRIPTION: RecName: Full=Oligodendrocyte transcription factor 2; Short=Oligo2; FUNCTION: Required for oligodendrocyte and motor neuron specification in the spinal cord, as well as for the development of somatic motor neurons in the hindbrain. Cooperates with OLIG1 to establish the pMN domain of the embryonic neural tube. Antagonist of V2 interneuron and of NKX2-2-induced V3 interneuron development. SUBUNIT: Interacts with NKX2-2. INTERACTION: P41136:Id2; NbExp=4; IntAct=EBI-1213740, EBI-309167; P41139:Id4; NbExp=5; IntAct=EBI-1213740, EBI-1213725; SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=The NLS contained in the bHLH domain could be masked in the native form and translocation to the nucleus could be mediated by interaction either with class E bHLH partner protein or with NKX2-2. TISSUE SPECIFICITY: Expressed specifically in the brain. DEVELOPMENTAL STAGE: Expressed in the ventral spinal cord as early as 9.5 dpc. Expression becomes progressively restricted to a narrow zone within the ventral neuroepithelium of the spinal cord. In the 14.5 dpc spinal cord, expressed in the oligodendrocyte progenitors of the ventral ventricular zone, but not dorsal root ganglia Schwann cells. Also expressed scattered in the mantle zone, likely corresponding to oligodendrocyte progenitors migrating out from their site of origin. In the brain, from 10.5 through 14.5 dpc, expressed in numerous cells in the ventricular and subventricular zones of the lateral and medial ganglionic eminences, suggesting that expression might not be limited to the oligodendrocytic lineage. By 15.5 dpc, dispersed throughout the gray matter, with little or no residual expression in the ventricular zone. In the postnatal brain, present preferentially in the white matter, such as corpus callosum and cerebellar medulla. Expressed in the 13.5 and 14.5 dpc retina and in the olfactory epithelium from 11.5 dpc onward. INDUCTION: By SHH. Also induced by NKX6-1 in the developing spinal cord, but not in the rostral hindbrain. DOMAIN: The bHLH is essential for interaction with NKX2-2. SIMILARITY: Contains 1 bHLH (basic helix-loop-helix) domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
