Multiple binding interfaces of CD23. Two views of the cow CD23 structure highlighting residues that interact with various ligands. A, view of the CRD with the disaccharide binding site exposed. B, view of the opposite face of the CRD. Red, residues that bind to sugars. Blue, portions of human CD23 that bind to IgE. Green, integrin-binding regions of human CD23. The binding site for CD21 in human CD23 maps to a C-terminal extension.
