Target Information
Polymeric IgA and IgM are produced and secreted by B cells in the lamina propria beneath the mucosal lining of polarized epithelial cells. Polymeric immunoglobulin receptors (pIgRs) are expressed on the basolateral surface of glandular epithelia and mediate transcellular transport of secretory immunoglobulin polymers across the epithelium.
During this process, pIgR associates with secreted dimeric IgA and IgM molecules and undergoes proteolytic cleavage to generate a fragment called the secretory component (SC). When immunoglobulin polymers associate with SC, they become resistant to enzymatic degradation during transcytosis. SC and pIgR are crucial for proper mucosal immunity, acting as molecular chaperones for polymeric immunoglobulins to remain intact and enter body fluids.
The human SC (pIgR) gene maps to chromosome 1q31–q41 and encodes a 764-amino-acid protein. The receptor contains five units with homology to immunoglobulin variable (V) regions and a transmembrane domain sharing homology with certain immunoglobulin variable regions.
