BAMBI / NMA Protein Product Information

• Synonym: BAMBI, Nma
• Protein Construction: A DNA sequence encoding the mouse BAMBI (Q9D0L6)(Met1-Ala152) was expressed, fused with the Fc region of human IgG1 at the C-terminus.
• Source: Mouse
• Expression Host: Human Cells

BAMBI / NMA Protein QC Testing

• Purity: > 90% as determined by SDS-PAGE
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Stability: Samples are stable for up to twelve months from date of receipt at -70℃

BAMBI / NMA Protein Description

BMP and activin membrane-bound inhibitor (BAMBI) is a transmembrane glycoprotein that is a pseudoreceptor of type 1 receptors. BAMBI structurally lacks intracellular serine/threonine kinase domain but with an extracellular domain and a short cytoplasmic region that share sequence similarities with type 1 receptors, whose members have functions in signal transduction in various developing and pathological processes. BAMBI competes with the type 1 receptor, a receptor of the transforming growth factor- beta(TGF- beta) , through functioning as negative regulators of TGF-beta by limiting the signaling range of the TGF-beta family during early embryogenesis. The expression of BAMBI can be induced by accumulated beta- catenin and BMP. The expression level of BAMBI was found aberrantly elevated in most colorectal and hepatocellular carcinomas relative to the corresponding non-cancerous tissues. It suggestes that beta-catenin and TGF-beta interfere growth arrest by inducing the expression of BAMBI, and this may contribute to colorectal and hepatocellular tumorigenesis.
