背景（Background）
Ephrin-B2 (EFNB2) is also known as EPH-related receptor tyrosine kinase ligand 5 (LERK-5) or HTK ligand (HTK-L), which belongs to the ephrin family. The ephrin-B (ENFB) class are transmembrane proteins implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. EFNB2 has been shown to interact with EPHA3 and EPHB1 in optic chiasm development. EFNB2 has also been shown to serve as a receptor for Hendra Virus and Nipah Virus, mediating entry into the cell during infection.
