Studies of the spatial organization of the highly compartmentalized eukaryotic nucleus and dynamics of transcription and RNA processing within it are fundamental for fully understanding how gene expression is regulated in the cell. Although some progress has been made in deciphering the functional consequences of this complex network of interacting molecules in the context of nuclear organization, how proteins and RNA move in the nucleus and how the transcription and RNA processing machineries find their targets are important questions that remain largely unexplored. Here, we review major hallmarks and novel insights regarding the movement of RNA and proteins in the context of nuclear organization as well as the mechanisms by which the proteins involved in RNA processing localize to specific nuclear compartments.
