Summary: Enables cis-regulatory region sequence-specific DNA binding activity and protein heterodimerization activity. Contributes to DNA-binding transcription factor activity, RNA polymerase II-specific. Involved in brain segmentation; head morphogenesis; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including anterior-posterior subdivision of organism; gut section; midgut enterocyte; midgut primordium; and tritocerebrum. Human ortholog(s) of this gene implicated in Athabaskan brainstem dysgenesis syndrome and autistic disorder. Orthologous to human HOXA1 (homeobox A1); HOXB1 (homeobox B1); and HOXD1 (homeobox D1).
