Tbx3 Gene Summary [Rat]
Predicted to enable DNA-binding transcription factor 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 negative regulation of apoptotic process. Acts upstream of or within negative regulation of transcription by RNA polymerase II. Predicted to be part of transcription regulator complex. Predicted to be active in chromatin; cilium; and nucleus. Biomarker of myocardial infarction. Human ortholog(s) of this gene implicated in ulnar-mammary syndrome. Orthologous to human TBX3 (T-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 rat Tbx3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
