Original Article


Sex determining region Y-box 2 (Sox2) is a transcription factor that is essential for maintaining self-renewal or pluripotency of undifferentiated embryonic stem cells. The expression and distribution of Sox2 in tumor tissues have been extensively recorded, which are related to the progression and metastasis of tumor. However, a complete mechanistic understanding of Sox2 regulation and function remains to be studied. Herein, we show new potential properties of Sox2 regulation and functions from bioinformatics analysis. We use numerous algorithms to characterize the Sox2 gene promoter elements and the Sox2 protein structure, physio-chemical, localization properties and its evolutionary relationships. The expression of Sox2 is regulated by a diverse set of transcription factors and associated with the levels of methylation of CpG Islands in promoters. The structural properties of Sox2 indicate that Sox2 expresses as a stem cell marker in a variety of stem cells. Sox2 together with other transcription factors or proteins regulate the expression of downstream target genes, which makes a great difference to the biological function of stem cells. Not only stem cells, Sox2 also play an important role in tumor cells. In conclusion, this information from bioinformatics analysis will help to understand Sox2 regulation and functions better in future attempts.
