EFNB2 / EphrinB2蛋白背景綜述
The ephrins (Eph) and Eph receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosyl- phosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. All ephrins share a conserved extracellular sequence, which most likely corresponds to the receptor-binding domain. This conserved sequence consists of approximately 125 amino acids and includes four invariant cysteines. The cytoplasmic domains are approximately 80 amino acids long and are highly conserved, especially the last 33 amino acids. In molecular biology, ephrins and Eph receptors are components of cell signaling pathways involved in animal development, and implicated in some cancers. Eph receptors are classified as receptor tyrosine kinases (RTKs), and form the largest sub-family of RTKs. Almost all Eph receptors are expressed during various well defined stages of development in assorted locations and concentrations. Ephrin-B2 is a member of the ephrin ligand family, which binds members of the Eph receptor family. It has been shown to bind EphA4, EphB1, EphB2, EphB3, and EphB4. Ephrin-B2 plays a role in a variety of developmental processes, including arterial-venous differentiation, neural crest cell migration, and axon guidance.
