J chain- deficient mice have normal …
WebJCHAIN / Ig J Chain immunoglobulin J polypeptide, linker protein for immunoglobulin alpha and mu polypeptides Serves to link two monomer units of either IgM or IgA. In the case of IgM, the J chain-joined dimer is a nucleating unit for the IgM pentamer, and in the case of IgA it induces larger polymers. WebThe five primary classes of immunoglobulins are IgG, IgM, IgA, IgD, and IgE. These are distinguished by the type of heavy chain found in the molecule. IgG molecules have heavy chains known as gamma-chains; IgMs have …
