Source

Human Ephrin-A4, Fc Tag (EA4-H5250) is expressed from human 293 cells (HEK293). It contains AA Leu 26 - Gly 171 (Accession # AAI07484).

Predicted N-terminus: Leu 26

Molecular Characterization
Other Tags and Version Biotin & Other Labeled Version

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 43.0 kDa. The protein migrates as 45-50 kDa and 66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Background

Ephrin-A4 (EFNA4) is also known as EPH-related receptor tyrosine kinase ligand 4 (LERK4), EPLG4, which belongs to the ephrin family. EFNA4 contains one ephrin RBD (ephrin receptor-binding) domain. EFNA4 is 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. EFNA4 binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. EFNA4 may play a role in the interaction between activated B-lymphocytes and dendritic cells in tonsils.
