Anti-SMAD3 Rabbit Polyclonal Antibody
SMAD3, a member of 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. It 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. Smad 3 (Mothers against decapentaplegic homolog 3), a transcriptional regulator, is activated by TGF-beta and Activin 1 receptor kinase. SMAD3 recognizes an 8 bp palindromic sequence GTCTAGAC. Upon phosphorylation at two extreme C-terminal serines, SMAD3 is translocated into the nucleus where is forms complexes other SMAD proteins, depending on the activation pathway, and regulates the transcription of target genes.

SMAD3 antibody can be used in ELISA, Western Blot, and immunohistochemistry starting at 5 ?g/mL.
