Scientific Data Images for Mouse EphB3 Antibody

Detection of Mouse EphB3 antibody by Western Blot.

Detection of Mouse EphB3 by Western Blot.

Western blot shows lysates of mouse brain tissue. PVDF membrane was probed with 2 µg/mL of Rat Anti-Mouse EphB3 Monoclonal Antibody (Catalog # MAB432) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (HAF005). A specific band was detected for EphB3 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Mouse EphB3 by Western Blot.

Western blot shows lysates of A549 human lung carcinoma cell line and HT-29 human colon adenocarcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Rat Anti-Mouse EphB3 Monoclonal Antibody (Catalog # MAB432) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for EphB3 at approximately 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: EphB3

EphB3, also known as Cek10, Tyro6, Sek4, Hek2, and Mdk5, is a 130 kDa member of the transmembrane Eph receptor tyrosine kinase family. The A and B classes of Eph proteins are distinguished by Ephrin ligand binding preference but have a common structural organization. Eph-Ephrin interactions are widely involved in the regulation of cell migration, tissue morphogenesis, and cancer progression (1). The 525 amino acid (aa) extracellular domain (ECD) of mature mouse EphB3 contains a ligand binding domain followed by a cysteine rich region and two fibronectin type III domains. The 418 aa cytoplasmic domain contains a tyrosine kinase domain, a sterile alpha motif (SAM), and a PDZ binding motif (2). Within the ECD, mouse EphB3 shares 96% and 99% aa sequence identity with human and rat EphB3, respectively. Binding of EphB3 to its ligands Ephrin-B1, B2, and B3 triggers forward signaling through EphB3 as well as reverse signaling through the Ephrin (1, 3). EphB3 also interacts in cis with the receptor tyrosine kinase Ryk (4). Activation of its kinase is required for some but not all of the effects of EphB3 on cellular adhesion, motility, and morphology (5). EphB3 is widely expressed during development and in the adult; it shows a complementary tissue distribution to the Ephrin-B ligands (6‑9). EphB3 function is important in vascular, nervous system, thymocyte, and palate development (6, 7, 10‑12). It directs embyronic neuronal axon pathfinding, and its upregulation on local macrophages following neuronal injury promotes the growth of regenerating axons (10, 13). EphB3 inhibits colorectal carcinogenesis and invasion by preventing the migration of tumor cells out of the intestinal crypt (9, 14). EphB3 function is supported by the cooperative action of EphB2 in several of these processes (6, 10‑12, 15).
