Preparation and Storage

Background: Ephrin-B1

Ephrin-B1, also known as LERK-2, ELK-L, EFL-3, Cek5-L, and STRA-1 (1), is a member of the ephrin ligand family which binds members of the Eph receptor family. All ligands 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 B-class ligands are transmembrane proteins which can become tyrosine phosphorylated upon receptor ligation. The cytoplasmic domains are approximately 80 amino acids long and are highly conserved, especially the last 33 amino acids. Several signaling molecules have been shown to interact with the cytoplasmic region, although specific signaling roles have yet to be elucidated. Ephrin-B1 has been shown to bind EphA3, EphB1, EphB2, EphB3, and EphB4 (2, 3). The extracellular domains of human and mouse Ephrin-B1 share 94% amino acid identity. Only membrane‑bound or Fc-clustered ligands are capable of activating the receptor in vitro. Soluble monomeric ligands bind the receptor but do not induce receptor autophosphorylation and activation (2). In vivo, the ligands and receptors display reciprocal expression (3). It has been found that nearly all receptors and ligands are expressed in developing and adult neural tissue (3). The Eph/ephrin families also appear to play a role in angiogenesis (3).
