Predicted to enable DNA binding activity and DNA-binding transcription repressor activity, RNA polymerase II-specific. Predicted to be involved in central nervous system development; neuron differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including negative regulation of transcription by RNA polymerase II; nervous system development; and skeletal muscle cell differentiation. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in syndromic microphthalmia 11. Orthologous to human VAX1 (ventral anterior homeobox 1).
