SOX1 (for Sex determining region Y-box 1) is a transcription factor in the Sox protein family. SOX1 expression is restricted to neuroectoderm in the tetrapod embryo. [1 ] SOX1 is involved in early [2 ] central nervous system development, where it is functionally redundant with SOX3 and to a lesser degree SOX2, and maintenance of neural progenitor cell identity. SOX1 is expressed particularly in the ventral striatum, and Sox1-deficient mice have altered striatum development, leading e.g. to epilepsy. [1 ]
