Predicted to enable DNA-binding transcription factor activity and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of DNA-templated transcription. Predicted to be located in nucleus. Is an ortholog of C. elegans sea-1. In C. elegans, sea-1 is involved in dosage compensation by hypoactivation of X chromosome; positive regulation of transcription by RNA polymerase II; and sex determination.
