SOX5 (SRY-Related HMG-Box Gene 5): SOX5 is a member of the SOX family of transcription factors that play a key role in regulating embryonic development and determining cell fate. SOX5 is involved in several biological processes, including chondrogenesis, nervous system development, and the differentiation of various cell types. It functions by binding to DNA and controlling the expression of genes essential for cell growth, development, and specialization. Mutations or dysregulation of SOX5 have been linked to a range of developmental disorders and other pathological conditions.
