概要 Using a recombinant vaccinia virus containing the T7 RNA polymerase, we have established a system for the transient expression of human polymeric immunoglobulin receptor (pIgR) in baby hamster kidney cells, a baby hamster-derived fibroblastic cell line. This transfection system resulted in the successful expression of pIgR in these cells, and Western blot analysis showed that human pIgR was expressed as two different molecular weight forms of 92 and 107 kDa. Treatment with endoglycosidase H showed that the difference between these two forms was due to the glycosylation status of the protein. In order to examine the functional role of glycosylation, we treated the transfected cells with tunicamycin, which prevents a core glycosylation step in the endoplasmic reticulum. Non-glycosylated pIgR was released into the culture medium of the transfected cells, albeit with extremely low efficiency. Taking these results together, we conclude that the glycosylation of pIgR may play a positive role in the efficient transport or release of free pIgR.
