Background

The ephrin receptor B2 (EphB2) is an ephrin family receptor tyrosine kinase that plays an important role in regulating growth and development of multiple tissues and organs (1,2). The EphB2 transmembrane receptor protein contains a kinase domain, a PDZ motif, and a SAM domain within a conserved cytoplasmic domain. A ligand binding domain, a cysteine-rich domain, and fibronectin type III repeats comprise the conserved EphB2 extracellular domain (3). EphB2 binds with high affinity to ephrin B ligands, and to some ephrin A proteins, to initiate bidirectional signaling between neighboring cells (1,2). Upon binding, EphB2-Ephrin B2 dimers form a heterotetramer and position the receptor-ligand complex on the cell membrane to facilitate bidirectional signal transduction (3). In addition to associating with ephrin ligands, EphB2 also regulates a number of biological processes through interaction with focal adhesion kinase (FAK), NMDA receptor (NMDAR), the Rac1 guanine nucleotide exchange factor Tiam1, and p21-activated kinase (PAK1) (4-7). While some studies support a role for EphB2 as a pro-oncogenic kinase, other research suggests that EphB2 acts as a tumor suppressor (1,2,4,8).
