MHC class molecules r suppose to bind to intra cellular peptides n then translocate to the surfece of the cell to work properly..
in tis infected cell it is rather pumped out of ER into cytosol..
tis probably has happened due to defective post translational modification or due to the mutation in the coding gene,,
all the defective proteins in the cell r marked by ubiqitin to be later degraded in the proteosomes..so its C.. degraded in the proteosomes
