Atf3 - activating transcription factor 3

Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II transcription 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 nucleolus and nucleoplasm. Predicted to be part of CHOP-ATF3 complex. Predicted to be active in nucleus. Orthologous to human ATF3 (activating transcription factor 3). [provided by Alliance of Genome Resources, Apr 2022]
