Description | This entry represents the ligand-binding domain found in ephrin type-B receptor 1 (EphB1). Using EphB1 knockout-mice, EphB1 has been shown to be essential to the development of long-term potentiation (LTP) [ ], a cellular model of synaptic plasticity, learning and memory formation [, , ].Class EphB receptors bind to transmembrane ephrin-B ligands. There are six vertebrate EhpB receptors (EphB1-6), which display promiscuous interactions with three ephrin-B ligands [ ].Ephrin receptors (EphRs) comprise the largest subfamily of receptor tyrosine kinases (RTKs). EphRs contain a ligand binding domain and two fibronectin repeats extracellularly, a transmembrane segment, and a cytoplasmic tyrosine kinase domain. Binding of the ephrin ligand to EphR requires cell-cell contact since both are anchored to the plasma membrane. The resulting downstream signals occur bidirectionally in both EphR-expressing cells (forward signaling) and ephrin-expressing cells (reverse signaling) [ ]. |
