Atf3 Gene Summary [Rat]
Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of cell population proliferation and positive regulation of transcription by RNA polymerase II. Predicted to be located in Golgi apparatus; microtubule organizing center; and nuclear lumen. Predicted to be part of CHOP-ATF3 complex and RNA polymerase II transcription regulator complex. Predicted to be active in nucleus. Orthologous to human ATF3 (activating 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 Atf3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
