General annotation

Function Transcription factor that acts synergistically with SOX11 and SOX4. Plays a role in neuronal development. Is implicated in an enhancer activity at the embryonic met- mesencephalic junction; the enhancer element contains the octamer motif (5'-ATTTGCAT-3') (By similarity).
Subcellular location Nucleus.
