Recombinant human SAT (Special AT-rich sequence-binding) protein, also known as SATB1 or SATB2. is a chromatin-organizing factor crucial for regulating gene expression by shaping higher-order chromatin architecture. First identified in the 1990s, SAT proteins bind to AT-rich DNA sequences through their conserved CUT domains, acting as global transcriptional regulators. SATB1 plays a key role in T-cell development and breast cancer metastasis, while SATB2 is essential for neuronal differentiation, osteoblastogenesis, and craniofacial patterning. Dysregulation of SAT proteins is linked to cancers, neurological disorders, and developmental defects. Recombinant SAT proteins are typically produced using bacterial (e.g., *E. coli*) or mammalian expression systems, enabling studies on DNA-protein interactions, epigenetic regulation, and 3D genome organization. Their applications span structural biology, drug discovery, and gene therapy research. For instance, recombinant SATB1 is used to investigate immune cell function, while SATB2 aids in studying skeletal and neural development. Advances in recombinant technology have improved solubility and post-translational modification fidelity, enhancing their utility in biomedical research. Current studies focus on targeting SAT proteins for cancer immunotherapy and regenerative medicine.
