Abstract:
The molecular mechanisms by which the AP-1 transcription factor c-Jun exerts its biological functions are not clearlyunderstood. In addition to its well established role in transcriptionalregulation of gene expression, several reportshave suggested

Materials & Methods:
For photoswitch and fluorescence recovery after photobleaching (FRAP) studies, cells were transfected with PS-CFP2- DDX21, EGFP-DDX21 (15), or EGFP-DDX21 mut and grown on glass-bottom dishes (MatTek).
