Enables transcription cis-regulatory region binding activity. Involved in several processes, including negative regulation of transcription by RNA polymerase II; regulation of insulin secretion involved in cellular response to glucose stimulus; and type B pancreatic cell differentiation. Acts upstream of or within blastocyst hatching. Located in cytoplasm and nucleolus. Is expressed in early conceptus; nervous system; neural retina; and secondary oocyte. Orthologous to human ZBED6 (zinc finger BED-type containing 6). [provided by Alliance of Genome Resources, Apr 2022]
