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 chordate embryonic development; muscle structure development; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; regionalization; and regulation of transcription by RNA polymerase II. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human HOXA2 (homeobox A2). [provided by Alliance of Genome Resources, Apr 2022]
