Background: Ephrin-B1

Ephrin-B1, also known as Elk Ligand, LERK2, and Eplg2, is an approximately 45 kDa member of the Ephrin-B family of transmembrane ligands that bind and induce the tyrosine autophosphorylation of Eph receptors. The extracellular domains (ECD) of Ephrin-B ligands are structurally related to GPI-anchored Ephrin-A ligands. Eph‑Ephrin interactions are widely involved in the regulation of cell migration, tissue morphogenesis, and cancer progression. Ephrin-B1 preferentially interacts with receptors in the EphB family. The binding of Ephrin-B1 to EphB proteins also triggers reverse signaling through Ephrin-B1 (1, 2). Mature mouse Ephrin-B1 consists of a 212 amino acid (aa) ECD, a 21 aa transmembrane segment, and an 88 aa cytoplasmic domain (3, 4). Within the ECD, mouse Ephrin-B1 shares 94% and 98% aa sequence identity with human and rat Ephrin-B1, respectively. Ligation by EphB2 enhances shedding of a 35 kDa fragment of the Ephrin-B1 ECD (5). The residual membrane-bound portion is then cleaved by gamma-secretase to release the intracellular domain (6). Ephrin-B1 also associates in cis with Claudin-1, -4, and -5 (7, 8). It is expressed on glomerular podocyte slit diaphragms, developing thymocytes, peripheral T cells, monocytes, macrophages, vascular endothelial cells, cardiomyocytes, osteoclasts, and luteinizing granulosa cells in the ovary (8-13). In the developing nervous system, Ephrin-B1 plays a role in cellular migration, axon guidance, and presynaptic development (14-16). It also regulates developing thymocyte survival, monocyte migration, osteoclast differentiation and function, cardiac muscle morphogenesis, and tumorigenesis (5, 8, 10-12). Ephrin-B1 is up-regulated on reactive astrocytes and on macrophages and T cells found in atherosclerotic plaques (11, 17).
