Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific; HMG box domain binding activity; and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in several processes, including angiogenesis; embryonic skeletal system morphogenesis; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including animal organ development; blood vessel remodeling; and glossopharyngeal nerve morphogenesis. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human HOXA3 (homeobox A3). [provided by Alliance of Genome Resources, Apr 2022]
