Transcription factor SOX-3 is a protein that in humans is encoded by the SOX3 gene.[1][2][1]

This gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic brain development and in determination of cell fate. The encoded protein acts as a transcriptional activator.[3] Mutations in this gene have been associated with X-linked hypopituitarism (XH) and X-linked mental retardation. Patients with XH are male, have short stature, exhibit a mild form of mental retardation and present pan-hypopituitarism. [2] [4]
