Summaries for OLIG2 Gene

Entrez Gene Summary for OLIG2 Gene

  • This gene encodes a basic helix-loop-helix transcription factor which is expressed in oligodendroglial tumors of the brain. The protein is an essential regulator of ventral neuroectodermal progenitor cell fate. The gene is involved in a chromosomal translocation t(14;21)(q11.2;q22) associated with T-cell acute lymphoblastic leukemia. Its chromosomal location is within a region of chromosome 21 which has been suggested to play a role in learning deficits associated with Down syndrome. [provided by RefSeq, Jul 2008]

GeneCards Summary for OLIG2 Gene

OLIG2 (Oligodendrocyte Lineage Transcription Factor 2) is a Protein Coding gene. Diseases associated with OLIG2 include papillary glioneuronal tumor and dysembryoplastic neuroepithelial tumor. Among its related pathways are Neural Crest Differentiation. GO annotations related to this gene include protein homodimerization activity and HMG box domain binding. An important paralog of this gene is BHLHE23.

UniProtKB/Swiss-Prot for OLIG2 Gene

  • 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 (By similarity).
