CD40, also known as TNFR5, is a protein that exhibits defects in conserved residues necessary for feature annotation propagation. Specific residues missing in CD40 prevent the propagation of certain functional features associated with this protein. CD40 Protein, Rat (HEK293, His) is the recombinant rat-derived CD40 protein, expressed by HEK293 , with C-His labeled tag.
