CD23, a type II membrane receptor protein, recognizes four different ligands via its extracellular C-type lectin domain: immunoglobulin E (IgE), CD21, and the beta 2-integrins CD11b and CD11c. CD23 specifically interacts in a calcium-dependent manner, "lectin-like" with carbohydrate moieties expressed on CD21 and CD11b/c, but also "lectin-unlike" with protein epitopes on IgE. As a first step in analyzing the multiple binding specificities associated with CD23 in more detail, we report a detailed molecular model of the lectin-like domain of human CD23 (hCD23). The model was built based on information provided by X-ray structures of mannose binding protein (MBP) and E-selectin, both of which are members of the calcium-dependent (C-type) lectin superfamily. Sequence-structure comparisons suggest that hCD23 is structurally more similar to MBP than to E-selectin. The hCD23 model is compared to an independently derived model. Although the CD23-carbohydrate and CD23-protein interactions are both calcium dependent, analysis of the model suggests the presence of distinct binding sites for these ligands.
