Synthetic human SMAD7 peptide (aa367-384).

Recombinant Antibody. Recognizes human SMAD7. Applications: ELISA, ICC, PLA. Clone: SH585-IIC4. Isotype: Human IgG1. Formulation: Liquid. In PBS. The TGF-beta signaling pathway regulates key cell fate decisions during embryonic development and in adult homeostasis. This pathway is deregulated in many pathological conditions, including cancer, autoimmunity and fibrotic diseases. TGF-beta functions as a tumor suppressor in early tumors, inhibiting progression through the cell cycle. TGF-beta binds a heterotetrameric cell surface complex composed of type I and II serine/threonine kinase TGF-beta receptors (TGFBRI and TGFBRII). Ligand binding causes receptor phosphorylation and transmission of the signal to a class of intracellular intermediates, the receptor-regulated SMAD proteins. The SMAD family is divided into three subclasses: receptor regulated SMADs, (SMADs 1, 2, 3, 5 and 8); the common partner, (SMAD4) that functions via its interaction to the various SMADs; and the inhibitory SMADs, (SMADs 6 and 7). TGF-beta signaling pathways engage two specific receptor-regulated SMAD proteins, the SMAD2 and SMAD3. The C-terminal MH2 domains of the receptor-regulated SMADs are phosphorylated by the intracellular kinase domain of TGF-beta receptors. The receptor-regulated SMADs then interact with SMAD4 and translocate to the nucleus, where they act as transcriptional regulators. Although TGF-beta signaling engages the above three SMAD proteins, SMAD2, SMAD3 and SMAD4, there is a dominant role of SMAD3 as a mediator of both physiological, homeostatic signaling and of pathophysiological perturbed signaling in all diseases. The SMAD proteins are central nodes in the mechanisms of cross-talk between the TGF-beta pathway and other signaling pathways, including the Notch and Wnt signaling pathways. The SMAD proteins regulate multiple cellular processes, such as cell proliferation, apoptosis and differentiation. SMAD7, also known as Mothers Against Decapentaplegic homolog 7 (MADH7), inhibits selected pathways by binding directly to cell-surface receptors and preventing the activation-induced phosphorylation of other SMAD subunits.

O15105

This is an antibody developed by antibody phage display technology using a human naive antibody gene library. These libraries consist of scFv (single chain fragment variable) composed of VH (variable domain of the human immunoglobulin heavy chain) and VL (variable domain of the human immunoglobulin light chain) connected by a polypeptide linker. The antibody fragments are displayed on the surface of filamentous bacteriophage (M13). This scFv was selected by affinity selection on antigen in a process termed panning. Multiple rounds of panning are performed to enrich for antigen-specific scFv-phage. Monoclonal antibodies are subsequently identified by screening after each round of selection. The selected monoclonal scFv is cloned into an appropriate vector containing a Fc portion of interest and then produced in mammalian cells to generate an IgG like scFv-Fc fusion protein.
