The [KO Validated] Smad4 Monoclonal Antibody (CAB19116) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, developed in rabbits, exhibits high specificity and sensitivity in detecting SMAD4 in various cell types, making it ideal for research in developmental biology, cancer biology, and stem cell research.SMAD4, also known as Co-SMAD, plays a pivotal role in transducing TGF-beta signals into the nucleus, where it regulates the expression of genes involved in cell proliferation, differentiation, and apoptosis. Dysregulation of SMAD4 has been associated with various diseases, including cancer and developmental disorders.
This antibody is validated for use in WB, IHC-P, IP, ChIP, ELISA, CUT&Tag applications and has demonstrated reactivity against Human, Mouse, Rat samples.

This gene encodes a member of the Smad family of signal transduction proteins. Smad proteins are phosphorylated and activated by transmembrane serine-threonine receptor kinases in response to transforming growth factor (TGF)-beta signaling. The product of this gene forms homomeric complexes and heteromeric complexes with other activated Smad proteins, which then accumulate in the nucleus and regulate the transcription of target genes. This protein binds to DNA and recognizes an 8-bp palindromic sequence (GTCTAGAC) called the Smad-binding element (SBE). The protein acts as a tumor suppressor and inhibits epithelial cell proliferation. It may also have an inhibitory effect on tumors by reducing angiogenesis and increasing blood vessel hyperpermeability. The encoded protein is a crucial component of the bone morphogenetic protein signaling pathway. The Smad proteins are subject to complex regulation by post-translational modifications. Mutations or deletions in this gene have been shown to result in pancreatic cancer, juvenile polyposis syndrome, and hereditary hemorrhagic telangiectasia syndrome.
