SMAD1
SMAD1 (MADH1, MADR1, BSP1, JV41), Gene ID 4086, is a receptor-regulated Smad transcription factor mediating BMP signaling via C-terminal SSXS phosphorylation, SMAD4 complexing, and MAPK/GSK3-SMURF1-regulated degradation; essential for bone development.
SMAD2
SMAD2 (MADR2, MADH2, gene ID 4087, 18q21.1) encodes a receptor-regulated Smad transducing TGF-β and activin signals; phosphorylated by the type I receptor, it joins Smad4, enters the nucleus via its MH2 domain, and is essential for mesoderm formation.
SMAD3
SMAD3 (SMAD family member 3, aliases MADH3, LDS3, JV15-2) is a human gene at 15q22.33 encoding a TGF-β pathway signal transducer, DNA-binding transcription factor, and tumor suppressor; mutations cause aneurysms-osteoarthritis syndrome and Loeys-Dietz syndrome 3.
SMAD4
SMAD4 (DPC4, MADH4), a tumor suppressor gene on 18q21.2 encoding the common-mediator SMAD of TGF-β/BMP signaling; germline variants cause juvenile polyposis, JPS-HHT overlap, and Myhre syndrome, and somatic loss occurs in about 50% of pancreatic cancers.
SMAD5
SMAD5 (MADH5), human gene on 5q31.1 encoding a BMP-pathway receptor-regulated Smad transcription factor with MH1/MH2 domains; implicated in familial pulmonary arterial hypertension, congenital heart disease, and development.
SMAD6
SMAD6 (SMAD family member 6, Gene ID 4091, 15q22.31) encodes the inhibitory Smad6 protein, a BMP-selective intracellular antagonist of TGF-β superfamily signaling; mutations cause craniosynostosis, congenital heart disease, and radioulnar synostosis.
SMAD7
SMAD7 (SMAD family member 7, MADH7) is a human inhibitory SMAD protein and gene on 18q21.1 that antagonizes TGF-beta signaling by blocking Smad2/3 receptor binding and recruiting SMURF ubiquitin ligases; dysregulated in Crohn's disease, fibrosis, and colorectal cancer.
