IMMUNOGLOBULINS, J-CHAIN

The immunoglobulin fragments found in the easy chain fractions of secretory IgA and polymeric IgM in a ratio of one j chain for one IgA dimer or one IgM pentamer. It is a polypeptide with a molecular weight of about 17 kD and perhaps serves either to bind the components of the globulins together or to transfer the globulins across membranes.
