Tbr1 Gene Summary [Mouse]
Enables DNA-binding transcription factor activity; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin DNA binding activity. Involved in cerebral cortex development; chromatin remodeling; and gene expression. Acts upstream of or within several processes, including brain development; conditioned taste aversion; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; heart; and sensory organ. Used to study autism spectrum disorder. Orthologous to human TBR1 (T-box brain transcription factor 1). [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 Tbr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
