Predicted to enable transcription corepressor activity. Predicted to be involved in several processes, including intestinal epithelial cell differentiation; negative regulation of Notch signaling pathway; and positive regulation of neuron projection development. Predicted to act upstream of or within epithelial cell differentiation and negative regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. Orthologous to human CBFA2T2 (CBFA2/RUNX1 partner transcriptional co-repressor 2). [provided by Alliance of Genome Resources, Apr 2022]
