Technical Data
SMAD 1/5/8/9 (Small Mothers against Decapentaplegic Deleted in Pancreatic Carcinoma)
SMADs are members of the MAD-related family of molecules. MAD-related proteins are a family of intracellular proteins that are essential components in the signaling pathways of the serine/threonine kinase receptors of the transforming growth factor beta superfamily (1). SMADs can be divided into receptor-regulated SMADs (R-SMADs: SMAD1, 2, 5, 8 and 9), common-mediator SMAD (co-SMAD: SMAD4), and inhibitory SMADs (I-SMADs: SMAD6 and 7). SMAD1, 5, 8 and 9 have high degrees of homology and antibodies are available that recognize sequences common to all of them. SMAD8 and SMAD9 are typically used as alternate names for one another in the literature. For additional information on SMAD proteins, please follow the provided links to the NCBI website: human SMAD1, SMAD2, SMAD3, SMAD4, SMAD5, SMAD6, SMAD7, SMAD9 and mouse SMAD8.
