**Background of PAX2 Recombinant Protein**
PAX2 (Paired Box 2) is a transcription factor encoded by the *PAX2* gene, a member of the PAX family critical for embryonic development. It plays a pivotal role in organogenesis, particularly in the formation of the kidneys, eyes, ears, and central nervous system. PAX2 regulates cellular differentiation, proliferation, and survival by binding to specific DNA sequences and modulating the expression of target genes involved in developmental pathways, such as Wnt and Notch signaling.
Structurally, PAX2 contains a paired box domain for DNA binding and a partial homeodomain, enabling its function as a transcriptional activator or repressor. Dysregulation of PAX2 is linked to congenital anomalies, including renal-coloboma syndrome, and aberrant expression has been observed in cancers like renal cell carcinoma and ovarian cancer, where it may promote tumor progression.
Recombinant PAX2 protein is engineered *in vitro* using expression systems (e.g., *E. coli* or mammalian cells) to produce a purified, biologically active form. This tool is vital for studying PAX2’s molecular mechanisms, including its interactions with DNA or proteins, and for developing assays to identify modulators of its activity. Researchers also utilize recombinant PAX2 in cell culture or animal models to investigate its role in tissue regeneration or disease pathogenesis.
Overall, PAX2 recombinant protein serves as a key resource for advancing developmental biology research and exploring therapeutic strategies for PAX2-associated disorders.
