SMAD2 Antibody

SMAD family member 2, also known as MADR2, and MADH2 (Mothers against decapentaplegic homolog 2), is a protein that in humans is encoded by the SMAD2 gene. It belongs to the SMAD family of proteins similar to the gene products of the Drosophila gene 'mothers against decapentaplegic' (Mad) and the C. elegans gene 'Sma.' The gene has been mapped to 18q21.1, a region which is frequently deleted in colorectal cancers. SMAD2 mediates the signal of the transforming growth factor (TGF)-beta, and thus regulates multiple cellular processes, such as cell proliferation, apoptosis, and differentiation. This protein is recruited to the TGF-beta receptors through its interaction with the SMAD anchor for receptor activation (SARA) protein. In response to TGF-beta signal, this protein is phosphorylated by the TGF-beta receptors.
