• Entrez Summary: N/A
• UniProt Summary: DNA-binding transcriptional regulator and coregulator that recognizes and binds to the consensus octamer binding site 5'-AT[A/T]A[T/A]T[A/T]A-3' in promoter of target genes (PubMed:19266028, PubMed:23805044). Plays a fundamental role in the gene regulatory network essential for retinal ganglion cell (RGC) differentiation. Cooperates with the transcription factor ISL1 to achieve RGC fate specification in the developing retina. Plays also a role in RGC axon formation and guidance by regulating gene expression of specific target genes. Plays a role in TNFSF11- mediated terminal osteoclast differentiation. Binds chromatin at promoter region of target genes (By similarity). {ECO:0000250|UniProtKB:Q63934, ECO:0000269|PubMed:19266028, ECO:0000269|PubMed:23805044}. Isoform 2: Acts either as a transcriptional activator or repressor (PubMed:23805044). Stimulates the promoter activity of the neuronal nicotinic acetylcholine receptor alpha CHRNA2. Negatively regulates the apoptosis regulator BAX promoter activity. Inhibits promoter activity of the neuronal intermediate filament protein alpha-internexin INA gene. Plays a role in the regulation of breast cancer cell growth by promoting transcription activation as well as repression of specific target genes. Involved in tumor breast progression and invasion (By similarity). Inhibits the promoter activity of the GTP-binding protein RIT2 gene containing the octamer binding site in retinal ganglion cells (PubMed:23805044). Plays also a role either as transcriptional coactivator or corepressor. Transcriptional coactivator cooperating with transcription factors TP53 to potentiate transcriptional activation of BAX promoter activity, and hence increases neuronal cell apoptosis. Antagonizes the transcriptional stimulatory activity of POU4F1 by preventing its binding to the octamer motif. Acts also as a transcriptional coactivator via its interaction with the transcription factor ESR1 (By similarity). {ECO:0000250|UniProtKB:Q63934, ECO:0000269|PubMed:23805044}.
