SMAD3, a member of the SMAD family of proteins, is involved in TGF-beta signaling cascade. A human homolog of Drosophila Mad protein, SMAD3 consists of N-terminal DNA-binding MH1 domain, a linker region and a C-terminal MH2 domain. It is a receptor regulated SMAD (R-SMAD) that functions downstream of TGF-beta and activin receptors and mediates their signaling. SMAD3 is recruited by SARA (Smad anchor for receptor activation) to the receptor kinase for phosphorylation. Upon phosphorylation, SMAD3 disassociates from SARA, forms a complex with SMAD4 and transmigrates into the nucleus where it complexes with other cofactors and acts as a transcription factor. It has an indispensable role in cell proliferation, differentiation, apoptosis and formation of ECM. Loss of SMAD3 results in Childhood T-cell leukemia.

FAQs for Smad3 Antibody (NB100-56479). (Showing 1 - 1 of 1 FAQs).

  1. I was wondering if you can recommend any primary polyclonal Smad3 antibody (reactivity: human) for gel supershifts?
    • We do provide a wide range of Smad3 antibodies, but unfortunately none of them have been tested for gel shift assay, so we can't guarantee they will work for an application never tested before.
