The IgD C(H)1 region contains the binding site for the human respiratory pathogen Moraxella catarrhalis IgD-binding protein MID.
(2006) In European Journal of Immunology 9(Sep;36). p.2525-2534- Abstract
- The Moraxella catarrhalis IgD-binding protein (MID) has a unique specificity for human IgD, and the sequence with maximal IgD binding is located within the amino acids MID962-1200. In the present paper, we examined the MID binding site on IgD using a series of recombinant Ig. Full-length IgD, IgD F(ab')(2), and an IgD F(ab') C290R mutant lacking the inter-heavy-chain cysteine 290 were manufactured. Furthermore, a series of IgD/IgG chimeras were constructed. ELISA, dot blot and flow cytometry were used to study the binding of purified Ig to native MID, recombinant MID912-1200 or to Moraxella with or without MID. MID962-1200 bound both the IgD F(ab')(2) and F(ab') C290R, indicating that the binding occurred independently of antibody... (More)

MID962-1200 bound both the IgD F(ab')(2) and F(ab') C290R, indicating that the binding occurred independently of antibody structure. When amino acids 157-224 of the IgD C(H)1 region were substituted with IgG sequences, binding by M. catarrhalis or recombinant MID962-1200 was abolished. Subsequent smaller substitutions of IgD C(H)1 157-224 with IgG sequences led us to conclude that IgD C(H)1 amino acids 198-206 were crucial for the interaction between MID and IgD. (Less)
