Analysis Note

The biological activity is measured by its ability to bind recombinant mouse ephrin-B1/Fc in an ELISA assay.

Biochem/physiol Actions

Member of Eph receptor tyrosine kinase family shown to bind ephrin-B1, ephrin-B2, and ephrin-B3; involved in pattern formation and morphogenesis, and in arterial/venous demarcation of the developing vasculature.

EphB3 (Epherin receptor B3) is involved in the development and plasticity of glutamatergic synapses, and their interaction with NMDA receptor. It can also regulate the processing of acute inflammatory pain, and mechanical allodynia as a result of nerve crush. In damaged adult cortex, this receptor promotes receptor-mediated cell apoptosis, which in turn is repealed by the action of ephrinB3 on EphB3. EphB3 and EphB2 reverse signaling plays an essential role for the formation of ventral cochlear nucleus (VCN) projections to medial nucleus of the trapezoid body (MNTB). It also plays a key role in the modulation of the survival of thymic epithelial cells (TECs), and their inactivation is related to elevated apoptotic incidence.

Other Notes

Extracellular domain of mouse EphB3 (amino acids 1-530) fused to the C-terminal 6X histidine-tagged Fc region of human IgG1 via a polypeptide linker.

Physical form

Lyophilized from a 0.2 μm filtered solution in 20 mM Tris, pH 8.0.

General description

EphB3 (Epherin receptor B3) is a receptor tyrosine kinase (RTK), which belongs to a 13 member family of ephrin receptors. This family is divided into two classes A and B. EphB3 belongs to EphB group, which contains five members. The ligands to this group of receptors are named ephrin-B1-B3. It is a bidirectional functioning membrane protein.
