Tbx20 Gene Summary [Mouse]
Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and RNA polymerase II-specific DNA-binding transcription factor binding activity. Involved in several processes, including heart development; mesenchymal cell development; and regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including circulatory system development; negative regulation of SMAD protein signal transduction; and regulation of DNA-templated transcription. Located in cytoplasm and nucleus. Is expressed in several structures, including early conceptus; genitourinary system; heart; hindbrain; and sensory organ. Used to study dilated cardiomyopathy. Human ortholog(s) of this gene implicated in atrial heart septal defect; atrial heart septal defect 4; congenital heart disease; tetralogy of Fallot; and ventricular septal defect. Orthologous to human TBX20 (T-box transcription factor 20). [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 Tbx20 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
