General description

SMAD7 (mothers against decapentaplegic homolog 7) is a Tbx1 (T-box 1) interacting gene and is encoded by the gene mapped to human chromosome 18q21.1.

SMAD7 (mothers against decapentaplegic homolog 7), that binds the E3 ubiquitin ligase Smurf1/2. SMAD7 belongs to the family of inhibitory Smads (I-Smads).

Immunogen

peptide corresponding to the N-terminal region of human SMAD7, conjugated to KLH. The corresponding sequence is identical in monkey and differs by 2 amino acids in mouse and rat.

Application

Anti-SMAD7 (N-terminal) antibody produced in rabbit has been used in immunoblotting and immunofluorescence.

Biochem/physiol Actions

SMAD7 (mothers against decapentaplegic homolog 7) is a modulator of TGFβ (transforming growth factor β) signaling in immune cells which are associated with ulcerative colitis and inflammatory bowel syndrome. It plays a major role in the etiology of CRC (colorectal cancer). In addition, it also acts as a mediator of the negative feedback loop for both the TGFβ and BMP (bone morphogenetic proteins) signaling pathways. It is essential for the remodelling of pharyngeal artery and the enlargement of great vessel. In mouse, homozygous removal of Smad7 causes primarily fourth-related arch artery defects. Silencing of Smad7 in RCD (refractory coeliac disease) biopsy samples can decrease the expression of interleukin-6 and tumour necrosis factor-α. Polymorphism of this gene is associated with colorectal cancer. SMAD7 is an inhibitor of the TGFβ (transforming growth factor beta) /BMP (bone morphogenetic proteins) pathway.
