Summary: 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 cell surface receptor protein serine/threonine kinase signaling pathway; cellular response to glucose stimulus; and regulation of gene expression. 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 Loeys-Dietz syndrome 6; Lynch syndrome; cervical cancer; and ovarian cancer. Orthologous to human SMAD2 (SMAD family member 2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
