Description
This gene encodes a member 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. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. The ephrin receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. The protein encoded by this gene functions as a receptor for ephrin A2, A3 and A5 and plays a role in short-range contact-mediated axonal guidance during development of the mammalian nervous system.
Form
Supplied as a 0.2 μm filtered solution in MES, NaCl, PEG, CHAPS and Imidazole.
Bio-activity
Measured by its binding ability in a functional ELISA. When Recombinant Human EphA8 Fc Chimera is coated at 2 μg/mL (100 μL/well), the concentration of Biotinylayed Recombinant Human Ephrin-A5 Fc Chimera that produces 50% of the optimal binding response is 2-12 ng/mL.
