应用 | Western Blot(0.1 µg/mL) Immunohistochemistry(5-15 µg/mL) |
目标/特异性 | Detects mouse Activin RIB/ALK‑4 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 50% cross‑reactivity with recombinant human (rh) Activin RIB is observed, 5% cross‑reactivity with rhActivin R1A is observed and less than 1% cross‑reactivity with rhActivin RIIA and rhActivin RIIB is observed. |
使用方法 | Western Blot: 0.1 µg/mL Immunohistochemistry: 5-15 µg/mL Blockade of Receptor-ligand Interaction: In a functional ELISA, 1-4 µg/mL of this antibody will block 50% of the binding of 50 ng/mL of Recombinant Mouse Cripto (Catalog # 1538‑CR) to immobilized Recombinant Mouse Activin RIB/ALK-4 Fc Chimera (Catalog # 1477‑AR) coated at 1 µg/mL (100 µL/well). At 30 μg/mL, this antibody will block >90% of the binding. |

背景 | Activin RIB, also known as ALK-4, is a glycosylated 58 kDa type I transmembrane receptor that belongs to the superfamily of TGF-beta serine/threonine kinase receptors. Activin RIB associates with Activin RIIB to form a receptor complex for activin and inhibin molecules (1). These ligands bind to Activin RIIB which then associates with, and phosphorylates, the cytoplasmic domain of Activin RIB to initiate signal transduction (2, 3). Mature mouse Activin RIB consists of a 103 amino acid (aa) extracellular domain (ECD), a 23 aa transmembrane segment, and a 356 aa cytoplasmic region that includes the kinase domain (4). Within the ECD, mouse Activin RIB shares 93% and 98% aa sequence identity with human and rat Activin RIB, respectively. It shares 23%‑38% aa sequence identity with other mouse type I receptors Activin RIA, BMPR-IA, BMPR-IB, and TGF-beta RI. Activin receptor signaling is modulated by the direct interaction of Activin RIB with cripto or inhibin binding protein (5‑7). Activin RIB is excluded from the signaling complex if Activin RIIB first binds inhibin and betaglycan (8). Activin RIB functions in a wide variety of growth and differentiation processes, including embryonic cell fate and axis determination, cell proliferation, apoptosis, and tumorigenesis (1, 9, 10). |
