Predicted to enable DNA-binding transcription activator 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 camera-type eye development; hypothalamus development; and limb development. Predicted to be located in nucleus. Is expressed in several structures, including central nervous system; eye; genitourinary system; hemolymphoid system; and neural ectoderm. Human ortholog(s) of this gene implicated in isolated microphthalmia 3. Orthologous to human RAX (retina and anterior neural fold homeobox). [provided by Alliance of Genome Resources, Apr 2022]
