背景信息

STAG2 is a subunit of the cohesin complex, a multi-protein assembly critical for chromosome segregation, DNA repair, and transcriptional regulation. The cohesin complex, composed of SMC1. SMC3. RAD21. and STAG proteins, mediates sister chromatid cohesion during cell division and facilitates 3D genome organization. Among the two paralogous STAG subunits in vertebrates, STAG2 is ubiquitously expressed, while STAG1 is enriched in specific tissues. STAG2 mutations are recurrently observed in cancers, including acute myeloid leukemia (AML), bladder cancer, and Ewing sarcoma, often associated with genomic instability and poor prognosis.

STAG2-specific antibodies are widely used to study cohesin dynamics, protein interactions, and functional alterations in disease. These antibodies enable detection of STAG2 expression levels via Western blot, immunofluorescence, or immunohistochemistry, aiding research on its role in chromatin looping, gene regulation, and aneuploidy. Commercially available clones (e.g., D9O7A from Cell Signaling Technology, EPR17430 from Abcam) are typically raised against human STAG2 epitopes, with validation in knockout cell lines to confirm specificity. Cross-reactivity with STAG1 remains a concern, necessitating careful validation. Studies using STAG2 antibodies have revealed its tumor-suppressive functions, including maintenance of chromosomal integrity and regulation of Wnt/β-catenin signaling. Emerging therapeutic strategies targeting cohesin-deficient cancers further highlight the biomarker potential of STAG2 loss, driving continued demand for reliable research tools.
