SMAD family member 6, also known as SMAD6, is a protein that in humans is encoded by the SMAD6 gene.^[5]

SMAD6 is a protein that, as its name describes, is a homolog of the

's gene products. There are two known isoforms of this protein.

Nomenclature

The SMAD proteins are homologs of both the drosophila protein, mothers against decapentaplegic (MAD) and the C. elegans protein SMA. The name is a combination of the two. During Drosophila research, it was found that a mutation in the gene MAD in the mother repressed the gene decapentaplegic in the embryo. The phrase "Mothers against" was added as a humorous take-off on organizations opposing various issues e.g., Mothers Against Drunk Driving, or MADD; and based on a tradition of such unusual naming within the gene research community.^[6]

Disease associations

Heterozygous, damaging mutations in SMAD6 are the most frequent genetic cause of non-syndromic craniosynostosis identified to date.^[7]

Interactions

Mothers against decapentaplegic homolog 6 has been shown to

with:

• HOXC8,^[8]
• MAP3K7,^[9][10]
• Mothers against decapentaplegic homolog 7,^[11]
• PIAS4,^[12] and
• STRAP.^[13]
