SOX2 (SRY-related HMG-box 2) is a transcription factor belonging to the SOX protein family, which plays a pivotal role in embryonic development and maintaining pluripotency. It is essential for the self-renewal of embryonic stem cells (ESCs) and the determination of cell fate during differentiation. SOX2 is particularly critical in early embryogenesis, such as neural ectoderm formation, and in sustaining the identity of progenitor cells in adult tissues, including the brain, retina, and respiratory epithelium. Dysregulation of SOX2 is linked to developmental disorders, cancer progression, and degenerative diseases.
Recombinant SOX2 protein is produced via molecular cloning techniques, typically expressed in bacterial or mammalian systems to ensure proper post-translational modifications. This engineered protein retains the functional domains of native SOX2. including the high-mobility group (HMG) DNA-binding domain, enabling it to interact with target gene promoters. Recombinant versions are standardized for purity and activity, making them valuable tools for studying mechanisms of pluripotency, cellular reprogramming, and disease pathways.
In research, recombinant SOX2 is widely used to induce pluripotent stem cells (iPSCs) when combined with other factors like OCT4. KLF4. and c-MYC. It also aids in modeling neurodevelopmental disorders and exploring regenerative therapies for conditions such as retinal degeneration or spinal cord injury. However, its oncogenic potential in certain contexts necessitates careful experimental design.
Commercial recombinant SOX2 often includes tags (e.g., His-tag) for purification and detection. Quality control involves assays verifying its ability to activate pluripotency genes or bind DNA sequences. Despite challenges in delivery and stability, recombinant SOX2 remains a cornerstone in developmental biology and translational medicine, bridging basic research and therapeutic innovation.
