Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of DNA-templated transcription. Predicted to act upstream of or within proteolysis. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome classic-like 2. Orthologous to human AEBP1 (AE binding protein 1).
