Predicted to enable several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; SMAD binding activity; and enzyme binding activity. Predicted to contribute to DNA binding activity and DNA-binding transcription factor activity. Involved in several processes, including adrenal gland development; regulation of gene expression; and transforming growth factor beta receptor signaling pathway. Located in cytoplasm and nucleus. Part of protein-containing complex. Used to study hepatocellular carcinoma. Biomarker of colon cancer and myocardial infarction. Human ortholog(s) of this gene implicated in Lynch syndrome; cervical cancer; and ovarian cancer. Orthologous to human SMAD2 (SMAD family member 2).
