| Description |
This Recombinant Human Ephrin-A5 (EFNA5) is expressed at the full length of the mature protein in mammalian cells, which corresponds to the 21-203aa region of human EFNA5. The protein has a TEV-linker and an immunoglobulin Fc domain fused on the C-terminus, with a molecular weight of 50.1 kDa. This protein product has a purity higher than 93%, as determined by SDS-PAGE. In the LSPR assay, it has an affinity constant of 13.8 nM against human EPHA3 protein. Also, the recombinant EFNA5 has an EC50 of 0.8674-1.119 ng/ml for binding to EPHA3, as determined by ELISA binding assay. The final product contains low endotoxin, with less than 1.0 EU/µg as determined by the LAL method. The EFNA5 is a promiscuous cell surface GPI-bound ligand that permits the cellular adhesion and contact-dependent directional signaling. The function of EFNA5 is vital for the nervous system development via axion fasciculation and the reorganization of the cytoskeleton. This product can be used in cancer research as cell adhesion reagent, ELISA reagent, and control for novel ligands for the associated ephrin receptor. |

| Function (From Uniprot) |
Cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Induces compartmentalized signaling within a caveolae-like membrane microdomain when bound to the extracellular domain of its cognate receptor. This signaling event requires the activity of the Fyn tyrosine kinase. Activates the EPHA3 receptor to regulate cell-cell adhesion and cytoskeletal organization. With the receptor EPHA2 may regulate lens fiber cells shape and interactions and be important for lens transparency maintenance. May function actively to stimulate axon fasciculation. The interaction of EFNA5 with EPHA5 also mediates communication between pancreatic islet cells to regulate glucose-stimulated insulin secretion. Cognate/functional ligand for EPHA7, their interaction regulates brain development modulating cell-cell adhesion and repulsion.
