Immunoglobulins are composed of two identical heavy chains and two identical light chains; disulfide-linked (PubMed:20176268). An IgD molecule contains thus a delta heavy chain combined with either a kappa or a lambda light chains. Kappa light chains are found predominantly on the membrane IgD (mIgD) form and lambda on the secreted IgD (sIgD) form, this fact is poorly understood. Membrane-bound IgD molecules are non-covalently associated with a heterodimer of CD79A and CD79B (PubMed:11282392).
