Background: EPHA4 is part of the ephrin receptor subfamily of the protein-tyrosine kinase family. EPH and EPH-related receptors have been implicated in mediating developmental events, particularly in the nervous system. The Eph family receptors can be divided into two groups, EphA and EphB, based on the sequence similarities of their extracellular domain. Expression of EphA4 is found predominantly is in the final stages of embryogenesis.
