POU3F2 (also known as OCT7 or BRN2) is a transcription factor belonging to the POU domain protein family, characterized by a conserved DNA-binding domain composed of a POU-specific (POU_S) subdomain and a POU homeodomain (POU_H). It plays critical roles in neurodevelopment, including the regulation of neuronal differentiation, maintenance of neural progenitor cell identity, and cortical layer formation. POU3F2 binds to specific DNA sequences to activate or repress target genes involved in cell fate determination and survival. Dysregulation of POU3F2 has been implicated in neurological disorders, such as Alzheimer’s disease, and cancers like melanoma, where it promotes tumor invasiveness and stem cell-like properties.
Recombinant human POU3F2 protein is engineered in vitro using expression systems (e.g., *E. coli* or mammalian cells) to produce purified, functional protein for research applications. This tool enables studies on DNA-protein interactions, transcriptional mechanisms, and cellular pathways modulated by POU3F2. Researchers also utilize it to screen potential therapeutics targeting POU3F2-driven pathologies or to model developmental processes. Its structure-function relationships, including post-translational modifications affecting activity, remain an active area of investigation. As a key regulator of cell identity, POU3F2 continues to offer insights into both basic biology and disease mechanisms.
