Ephrin B3 Protein, a member of the ephrin family, lacks conserved residue (s) crucial for feature annotation propagation. This unique molecular profile suggests distinct functional properties and interactions within the ephrin family. Investigating the specific role and implications of this divergence in conserved residues is crucial to understand Ephrin B3's functional nuances and cellular significance in biological processes. Ephrin B3 Protein, Rat (HEK293, His) is the recombinant rat-derived Ephrin B3 protein, expressed by HEK293 , with C-His labeled tag.
