EphB3, also known as Mdk5, Hek2, or Sek4, is a 993 amino acid (aa), 110kD member of the Eph family of tyrosine kinase receptors, which engage in bidirectional signaling with members of the ephrin transmembrane ligand family. EphB3 engages ephrin B ligands. Mouse EphB3 shares 99 and 97% aa identity with rat and and human EphB3, respectively, and ~62% identity with mouse EphB1 and EphB2, within the 525 aa extracellular domain. EphB receptors are involved in central nervous system axon guidance during development or injury. EphB3 also plays multiple roles in structural organization of pre- and postnatal intestine, skin, and thymus. Applications: Suitable for use in Western Blot. Other applications not tested.
