Anti-SOX10 (clone QR006)

SOX10 – Key Transcription Factor and Tumor Marker
Function and Biological Significance of SOX10
✔ SOX10 is a nuclear transcription factor that acts as a transport protein between the cytoplasm and the nucleus.
✔ It is crucial for the development of the neural crest and peripheral nervous system, as well as for:
  
Differentiation, maturation, and maintenance of Schwann cells
  
Function of melanocytes
SOX10 Expression in Normal Tissues
✔ SOX10 is expressed in:
  
Schwann cells and glial cells of the nervous system
  
Melanocyte nuclei
  
Epithelial cells of the salivary glands and mammary glands
SOX10 as a Tumor Marker
✔ SOX10 is a sensitive and specific marker for melanomas.
✔ Desmoplastic melanomas may only show focal positivity.
✔ SOX10 is also positive in melanocytic nevi.
✔ It shows high specificity for soft tissue tumors derived from the neural crest.
Summary
✔ SOX10 is a key transcription factor regulating the development of Schwann cells and melanocytes.
✔ It is expressed in melanocytes, neural cells, and glandular epithelial cells.
✔ In tumor diagnostics, SOX10 is a crucial marker for melanomas (including desmoplastic subtypes) and neural crest-derived neoplasms.
