Wild-type FLAG.CIITA8 was cotransfected with pDRA300CAT in the presence of control, pcDNA3, or different mutant forms of CIITA. The subsequent CIITA activity of each sample was assessed and the transdominant-negative function of the mutant constructs was calculated as (average of four experiments):
