Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in anatomical structure morphogenesis and response to salt stress. Located in nucleus. Expressed in ciliated neurons; interfacial epithelial cell; intestine; labial sensillum; and tail. Human ortholog(s) of this gene implicated in posterior polymorphous corneal dystrophy 1. Is an ortholog of human OVOL1 (ovo like transcriptional repressor 1) and OVOL2 (ovo like zinc finger 2).
