SATB2 (Special AT-rich sequence-binding protein 2) is a DNA-binding protein involved in chromatin remodeling and transcriptional regulation. It plays a critical role in embryonic development, particularly in the formation of the nervous system, skeletal structures, and intestinal epithelium. As a transcription factor, SATB2 modulates gene expression by organizing chromatin architecture and interacting with other regulatory proteins, such as Runx2 and Osterix, to coordinate osteoblast differentiation and bone formation.
In diagnostic pathology, SATB2 antibody is widely used as a sensitive and specific immunohistochemical marker for colorectal adenocarcinoma, aiding in distinguishing it from other gastrointestinal or metastatic cancers. SATB2 is expressed in over 95% of colorectal carcinomas, often alongside CK20 and CDX2. but shows limited expression in tumors of the upper gastrointestinal tract, lung, or ovary. It also serves as a marker for osteoblastic differentiation, helping identify osteosarcomas and metastatic bone lesions.
Notably, SATB2 expression is retained in metastatic colorectal cancers, making it valuable for tracking tumor origins. Its absence in most non-colorectal adenocarcinomas and mesenchymal tumors enhances its diagnostic utility. Additionally, SATB2 mutations are linked to developmental disorders like Glass syndrome, characterized by craniofacial and neurological abnormalities, further underscoring its biological significance.
