Detection of BMPR‑IB/ALK‑6 in PC‑3 Human Cell Line by Flow Cytometry. PC‑3 human prostate cancer cell line was stained with Mouse Anti-Human BMPR‑IB/|
ALK‑6 Monoclonal Antibody (Catalog # MAB5051, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')2 Secondary Antibody (Catalog # F0101B).
BMPR‑IB/ALK‑6 in PC‑3 Human Cell Line. BMPR‑IB/ALK‑6 was detected in immersion fixed PC‑3 human prostate cancer cell line using Mouse Anti-Human|
BMPR‑IB/ALK‑6 Monoclonal Antibody (Catalog # MAB5051) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to the cytoplasm and cell surface. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Cellular responses to bone morphogenetic proteins (BMPs) have been shown to be mediated by the formation of hetero-oligomeric complexes of the type I and type II serine/threonine kinase receptors. BMP receptor IB (BMPR-IB), also known as activin receptor-like kinase (ALK)-6, is one of seven known type I serine/threonine kinases that are required for the signal transduction of TGF-beta family cytokines. In contrast to the TGF-beta receptor system in which the type I receptor does not bind TGF-beta in the absence of the type II receptor, type I receptors involved in BMP signaling (including BMPR-IA, BMPR-IB/ALK-6, and ActR-I/ALK-2) can independently bind the various BMP family proteins in the absence of type II receptors. Recombinant soluble BMPR-IB binds BMP-4 with high-affinity in solution and is a potent BMP-4 antagonist in vitro. BMPR-IB is expressed in various tissues during embryogenesis. In adult tissues, BMPR-IB is only found in the brain. The extracellular domain of BMPR-IB shares little amino acid sequence identity with the other mammalian ALK type I receptor kinases, but the cysteine residues are conserved. Human and mouse BMPR-IB are highly conserved and share 98% amino acid sequence identity.
