SOX7 recombinant protein is a purified, biologically active form of the SOX7 transcription factor, engineered through recombinant DNA technology. Belonging to the SOX (SRY-related HMG-box) protein family, SOX7 contains a conserved high-mobility group (HMG) DNA-binding domain that enables sequence-specific interactions with regulatory regions of target genes. It plays critical roles in embryonic development, cell differentiation, and tissue homeostasis, particularly in cardiovascular formation, endoderm specification, and hematopoietic stem cell regulation. SOX7 is also implicated in tumor suppression, where it antagonizes oncogenic pathways like Wnt/β-catenin by disrupting β-catenin/TCF complexes or promoting its degradation.
Recombinant SOX7 is typically produced in heterologous expression systems (e.g., *E. coli* or mammalian cells) to ensure high purity and consistent activity. The protein often includes affinity tags (e.g., His-tag) for simplified purification and detection. Post-translational modifications, such as phosphorylation, may be preserved in eukaryotic expression systems to maintain native functionality. Quality control involves SDS-PAGE, Western blotting, and functional assays (e.g., DNA-binding ELISAs or luciferase reporter systems) to confirm structural integrity and bioactivity.
In research, SOX7 recombinant protein is widely used to study gene regulatory networks, model developmental processes, and investigate diseases like cancer or congenital disorders. It serves as a tool to rescue SOX7-deficient cellular phenotypes, modulate Wnt signaling in cancer models, or differentiate stem cells into specific lineages. Its therapeutic potential is being explored in regenerative medicine and targeted cancer therapies. However, challenges remain in optimizing delivery methods and understanding context-dependent interactions with other SOX family members (e.g., SOX17. SOX18) in complex biological systems.
