We show in this study that the nuclear localized form of ciita is a predominantly phosphorylated form of the protein, whereas cytoplasmic ciita is predominantly unphosphorylated. Novel phosphorylation sites were determined to be located within a region that contains serine residues 286, 288, and 293. Double mutations of these residues increased nuclear ciita, indicating that these sites are not required for nuclear import. Erk1/2-mediated phosphorylation of ciita down-regulates ciita activity by priming it for nuclear export, thus providing a means for cells to tightly regulate the extent of antigen presentation. |
