Function

Transcription factor that plays a key role in neuronal differentiation (By similarity). Binds preferentially to the recognition sequence which consists of two distinct half-sites, ('GCAT') and ('TAAT'), separated by a non-conserved spacer region of 0, 2, or 3 nucleotides (By similarity). Acts as a transcriptional activator when binding cooperatively with SOX4, SOX11, or SOX12 to gene promoters (By similarity). The combination of three transcription factors, ASCL1, POU3F2/BRN2 and MYT1L, is sufficient to reprogram fibroblasts and other somatic cells into induced neuronal (iN) cells in vitro (By similarity). Acts downstream of ASCL1, accessing chromatin that has been opened by ASCL1, and promotes transcription of neuronal genes (By similarity).

Supplementary info

Activity summary

Brn-2 also known as POU domain class 3 transcription factor 2 (POU3F2) is a transcription factor with a molecular weight of approximately 48 kDa. This protein plays a significant role in the development and function of the central nervous system. It is abundantly expressed in neuronal tissues and specific types of melanocytes. Brn-2 belongs to the POU domain family of proteins which are pivotal in regulating gene expression during development.

Biological function summary

Brn-2 regulates the expression of genes critical for neural differentiation and development. It acts as a transcriptional activator that binds to specific DNA sequences. Brn-2 does not act alone; it often participates in regulatory complexes with other transcription factors. Through these interactions Brn-2 influences the fate of neural progenitor cells and is involved in the regulation of neural stem cell maintenance.

Pathways

Brn-2 plays a role in the Wnt signaling pathway and the Notch signaling pathway. Both of these pathways are integral to cell fate determination during development. In the Wnt pathway Brn-2 may interact with proteins such as β-catenin which modulates the expression of genes involved in cell proliferation and differentiation. Additionally Brn-2's role in the Notch pathway can influence the activity of proteins like RBPJ impacting cell communication and developmental processes.

Associated diseases and disorders

Brn-2 has been linked to melanoma and gliomas. In melanoma Brn-2 can interact with other proteins such as MITF influencing melanocyte development and contributing to cancer progression. In glioma Brn-2's aberrant expression might affect cellular pathways that lead to uncontrolled proliferation and tumor formation. Understanding these connections provides insights into potential therapeutic targets for these conditions.
