Fig. 6. Forced expression of epiplakin fragments in immortalized wild-type mouse keratinocytes. Cells were transfected with indicated epiplakin cDNA constructs, and subjected to immunofluorescence microscopy either directly (left column) or after incubation with OA (+OA) for 5 hours. Epiplakin-GFP-fusion proteins expressed were visualized using antibodies as indicated. Merged images show colocalization of overexpressed fragments after OA incubation only in the cases of module 9 and PRD9. Scale bar: 10 µm.
