Six2 Gene Summary [Mouse]

Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including embryonic morphogenesis; kidney development; and positive regulation of chondrocyte proliferation. Acts upstream of or within several processes, including chondrocyte differentiation; condensed mesenchymal cell proliferation; and embryonic organ morphogenesis. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Used to study cleft palate. Human ortholog(s) of this gene implicated in renal Wilms' tumor. Orthologous to human SIX2 (SIX homeobox 2). [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 Six2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
