Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell differentiation; regulation of myelination; and regulation of transcription, DNA-templated. Predicted to act upstream of or within several processes, including negative regulation of transcription by RNA polymerase II; neurogenesis; and neuromuscular process controlling balance. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in spastic ataxia 8. Orthologous to human NKX6-2 (NK6 homeobox 2). [provided by Alliance of Genome Resources, Apr 2022]
