| pubmed-article:2071896 | pubmed:abstractText | HLA class II MHC molecule alpha- and beta-chains are normally synthesized in the presence of a third molecule, the invariant chain (Ii). Although Ii is not required for surface expression of HLA class II molecules, the influence of Ii on post-translational processing and maturation HLA class II molecules has not been thoroughly studied. In the present study, BALB/c 3T3 cells were transfected with HLA-DR alpha- and beta-chains with or without co-transfection with human Ii. Although Ii had no effect on the surface expression of DR, Ii did have a profound effect on the post-translational processing of both the alpha- and beta-chains. In the absence of Ii, the major species of alpha- and beta-chains were of lower m.w. than when expressed in the presence of Ii. The differences in m.w. were shown to be caused by differences in glycosylation with the majority of alpha- and beta-chains remaining unprocessed and endo H sensitive in the absence of Ii. The small proportion of alpha-chains that were processed in the absence of Ii showed an altered m.w. and altered sensitivity to treatment with endo H relative to alpha-chains processed in the presence of Ii. Pulse/chase studies demonstrated that although the majority of the alpha- and beta-chains remained unprocessed in the absence of Ii, the small amount that was processed was done so at a rate similar to that observed for alpha- and beta-chains processed in the presence of Ii. These studies demonstrate that Ii influences the post-translational processing of human class II molecules by affecting the proportion of alpha- and beta-chains that are processed and by determining the degree of processing of oligosaccharides on mature alpha-chains. | lld:pubmed |
