EFNB1 Cell surface transmembrane ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binding to Eph receptors residing on adjacent cells leads to contact-dependent bidirectional signaling into neighboring cells. Shows high affinity for the receptor tyrosine kinase EPHB1/ELK. Can also bind EPHB2 and EPHB3. Binds to, and induces collapse of, commissural axons/growth cones in vitro. May play a role in constraining the orientation of longitudinally projecting axons. Belongs to the ephrin family. Widely expressed (PubMed:8070404, PubMed:7973638). Detected in both neuronal and non-neuronal tissues (PubMed:8070404, PubMed:7973638). Seems to have particularly strong expression in retina, sciatic nerve, heart and spinal cord (PubMed:7973638). Note: This description may include information from UniProtKB.
