Predicted to enable transcription corepressor activity. Predicted to act upstream of or within DNA-templated transcription and negative regulation of DNA-templated transcription. Predicted to be located in nucleus. Is expressed in alar plate midbrain region; central nervous system; ectoderm; hindbrain neural plate; and mesoderm. Orthologous to human CBFA2T2 (CBFA2/RUNX1 partner transcriptional co-repressor 2).
