Predicted to enable SMAD binding activity and nuclear receptor coactivator activity. Predicted to be involved in several processes, including epigenetic maintenance of chromatin in transcription-competent conformation; regulation of nucleic acid-templated transcription; and transmembrane receptor protein serine/threonine kinase signaling pathway. Predicted to act upstream of or within several processes, including circulatory system development; positive regulation of fibroblast proliferation; and vitellogenesis. Predicted to be located in cytosol and nucleoplasm. Orthologous to human ZMIZ1 (zinc finger MIZ-type containing 1). [provided by Alliance of Genome Resources, Apr 2022]
