Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including angiogenesis; embryonic limb morphogenesis; and lung development. Predicted to be located in nucleus. Is expressed in several structures, including central nervous system; early conceptus; embryo mesenchyme; genitourinary system; and limb primordium. Human ortholog(s) of this gene implicated in ischiocoxopodopatellar syndrome. Orthologous to human TBX4 (T-box transcription factor 4). [provided by Alliance of Genome Resources, Apr 2022]
