Also known as: BRN2; OCT7; OTF7; OTF-7; POUF3; brn-2; oct-7; N-Oct3
Summary: This gene encodes a member of the POU-III class of neural transcription factors. The encoded protein is involved in neuronal differentiation and enhances the activation of corticotropin-releasing hormone regulated genes. Overexpression of this protein is associated with an increase in the proliferation of melanoma cells. [provided by RefSeq, Mar 2012]

Re4sults show that BRN2 is: directly transcriptionally repressed by AR, required for the expression of terminal neuroendocrine markers and aggressive growth of castration-resistant prostate cancer (CRPC), and is highly expressed in human neuroendocrine prostate cancer and metastatic CRPC with low circulating PSA.
Title: The Master Neural Transcription Factor BRN2 Is an Androgen Receptor-Suppressed Driver of Neuroendocrine Differentiation in Prostate Cancer.
These findings not only shed light on the molecular mechanism of the anticancer properties of capsaicin, but also the transcription regulation of tNOX expression that may potentially explain how POU3F2 is associated with tumorigenesis.
Title: Capsaicin Inhibited Aggressive Phenotypes through Downregulation of Tumor-Associated NADH Oxidase (tNOX) by POU Domain Transcription Factor POU3F2.
Data indicate that NFIB protein increases EZH2 protein expression downstream of BRN2 protein, which further decreases MITF protein levels.
Title: NFIB Mediates BRN2 Driven Melanoma Cell Migration and Invasion Through Regulation of EZH2 and MITF.
We show that POU3F2 lies downstreamof SIM1 and controls oxytocin expression in the hypothalamic neuroendocrine preoptic area. We show that this finding is consistent with the expression patterns of POU3F2 and related genes in the human brain.

BRN2 is a higher level regulator than ASCL1 and ND1 and BRN2 might be involved in aggressiveness of small cell lung cancer.
Title: POU domain transcription factor BRN2 is crucial for expression of ASCL1, ND1 and neuroendocrine marker molecules and cell growth in small cell lung cancer.
TTF1 expression in small-cell lung cancer is a cell lineage-specific phenomenon that involves the developing neural cell-specific homeoprotein BRN2.
Title: Neural lineage-specific homeoprotein BRN2 is directly involved in TTF1 expression in small-cell lung cancer.
The present study investigated transcriptional regulation of CDH13 in melanoma. Found an inverse correlation between BRN2 and T-cadherin protein and transcript expression in melanoma.
Title: BRN2 is a transcriptional repressor of CDH13 (T-cadherin) in melanoma cells.
PI3K has a crucial role in regulating Brn-2 and Pax3 expression and neoplasm invasiveness, and it is a key determinant of melanoma subpopulation diversity.
Title: A phosphatidylinositol 3-kinase-Pax3 axis regulates Brn-2 expression in melanoma.
links BRN2 as an activator and MITF as a repressor of the NOTCH pathway in melanoma cells. Loss of the BRN2-MITF axis in antisense-ablated cell lines decreased the melanoma sphere-forming capability and cell adhesion

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
