Mothers against decapentaplegic homolog 5 also known as SMAD5 is a protein that in humans is encoded by the SMAD5 gene.[5]
SMAD5, as its name describes, is a homolog of the Drosophila gene: "Mothers against decapentaplegic", based on a tradition of such unusual naming within the gene research community.[6] It belongs to the SMAD family of proteins, which belong to the TGFβ superfamily of modulators. Like many other TGFβ family members SMAD5 is involved in cell signalling and modulates signals of bone morphogenetic proteins (BMP's). The binding of ligands causes the oligomerization and phosphorylation of the SMAD5 protein. SMAD5 is a receptor regulated SMAD (R-SMAD) and is activated by bone morphogenetic protein type 1 receptor kinase. It may play a role in the pathway where TGFβ is an inhibitor of hematopoietic progenitor cells.
Clinical Significance
[edit source]Variants of SMAD5 are associated with congenital heart disease. They have autosomal dominant inheritance due to either haploinsufficiency or dominant-negative effect.[7]
