Predicted to enable RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and protein dimerization activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to be part of transcription regulator complex. Is an ortholog of C. elegans
efl-1. In C. elegans,
efl-1 is involved in several processes, including embryonic digestive tract morphogenesis; negative regulation of Ras protein signal transduction; and negative regulation of vulval development.
