Rabbit anti-Human Smad7 Polyclonal Antibody

Uniprot Id

O15105

Target Species

Human

Target Name

SMAD7

Target Full Name

Mothers against decapentaplegic homolog 7

Target Function

Antagonist of signaling by TGF-beta (transforming growth factor) type 1 receptor superfamily members; has been shown to inhibit TGF-beta (Transforming growth factor) and activin signaling by associating with their receptors thus preventing SMAD2 access. Functions as an adapter to recruit SMURF2 to the TGF-beta receptor complex. Also acts by recruiting the PPP1R15A-PP1 complex to TGFBR1, which promotes its dephosphorylation. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator.

Target Involvement

Colorectal cancer 3 (CRCS3)

Target Subcellular Location

Nucleus. Cytoplasm.

Target Protein Families

Dwarfin/SMAD family

Target Tissue Specificity

Ubiquitous with higher expression in the lung and vascular endothelium.

Target Background

The protein encoded by this gene is a nuclear protein that binds the E3 ubiquitin ligase SMURF2. Upon binding, this complex translocates to the cytoplasm, where it interacts with TGF-beta receptor type-1 (TGFBR1), leading to the degradation of both the encoded protein and TGFBR1. Expression of this gene is induced by TGFBR1. Variations in this gene are a cause of susceptibility to colorectal cancer type 3 (CRCS3). Several transcript variants encoding different isoforms have been found for this gene.
