SOX1 is a gene that encodes a transcription factor with a HMG-box (high mobility group) DNA-binding domain and functions primarily in neurogenesis. SOX1, SOX2 and SOX3, members of the SOX gene family (specifically the SOXB1 group), contain transcription factors related to SRY, the testis-determining factor.
SOX1 exerts its importance in its role in development of the central nervous system (neurogenesis) and in particular the development of the eye, where it is functionally redundant with SOX3 and to a lesser degree SOX2, and maintenance of neural progenitor cell identity. SOX1 expression is restricted to the neuroectoderm by proliferating progenitor cells in the tetrapod embryo.[5][6] The induction of this neuroectoderm occurs upon expression of the SOX1 gene. In ectodermal cells committed to a certain cell fate, SOX1 has shown to be one of the earliest transcription factors expressed.[7] In particular, SOX1 is first detected in the late head fold stage.[8]
