Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in animal organ development and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including nervous system development; regulation of respiratory gaseous exchange by nervous system process; and respiratory gaseous exchange by respiratory system. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human TLX3 (T cell leukemia homeobox 3). [provided by Alliance of Genome Resources, Apr 2022]
