Eph family of tyrosine kinase receptors mediates cell-cell attachment and aggregation by binding to specific ligands, ephrins. The Eph family consists of 14 structurally related receptors that are either membrane linked or are transmembrane with overlapping affinity for ligands. The transmembrane receptors EphA and EphB1 (ELK) subclasses signal via distinct mediators in the cytoplasm. EphB1 binds ephrinB1, recruits Grb2 and Grb10 and mediates cell attachment and cell-cell assembly. Activated EphB1 also reportedly mediates the signaling by c-Jun kinase. The EphB1 receptors are vital in targeting the migration of neurons, angiogenesis and vascular cell assembly during development Anti-EphB1 (Elk Receptor)-EXT recognizes the external region of human EphB1 protein (116 kDa).

Eph family receptor tyrosine kinases signal axonal guidance, neuronal bundling, and angiogenesis; yet the signaling systems that couple these receptors to targeting and cell-cell assembly responses are incompletely defined. Functional links to regulators of cytoskeletal structure are anticipated based on

Eph receptors and their ligands have been implicated in axonal pathfinding during the formation of neuronal networks. Whereas other guiding molecules, such as netrins and most semaphorins, are diffusible factors that can guide axons over considerable distances, Eph receptors and
In vertebrate embryos, neural crest cell migration and motor axon outgrowth are restricted to rostral somite halves by repulsive factors located in the caudal somite compartment. We show that two Eph family transmembrane ligands, Lerk2 and HtkL, are expressed in
Eph family receptor tyrosine kinases (including EphA3, EphB4) direct pathfinding of neurons within migratory fields of cells expressing gradients of their membrane-bound ligands. Others (EphB1 and EphA2) direct vascular network assembly, affecting endothelial migration, capillary morphogenesis, and angiogenesis. To explore
