Ephrin-A3/EFNA3 Protein, a GPI-bound ligand, interacts with Eph receptors, playing a critical role in neuronal, vascular, and epithelial development. It binds adjacent Eph receptors, initiating bidirectional signaling. Ephrin-A3/EFNA3 also activates EPHA8, contributing to its regulatory functions in migration, repulsion, and adhesion. Ephrin-A3/EFNA3 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived Ephrin-A3/EFNA3 protein, expressed by HEK293 , with C-hFc labeled tag.
