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 located in nucleus. Predicted to be part of transcription regulator complex. 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, Apr 2022]
