Sox3 Gene Summary [Mouse]
Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including Sertoli cell development; diencephalon development; and face development. Acts upstream of or within animal organ morphogenesis; forebrain development; and spermatid differentiation. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including brain; branchial arch; early conceptus; embryo ectoderm; and gonad. Used to study hydrocephalus. Human ortholog(s) of this gene implicated in X-linked panhypopituitarism. Orthologous to human SOX3 (SRY-box transcription factor 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Sox3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
