Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within anterior/posterior pattern specification; brain development; and inner ear morphogenesis. Predicted to be active in nucleus. Orthologous to human OTX1 (orthodenticle homeobox 1). [provided by Alliance of Genome Resources, Apr 2022]
